TiDB automatically determines whether to select the MPP mode using the optimizer's cost estimation. You can change the selection strategy by modifying the values of [`tidb_allow_mpp`](/system-variables.md#tidb_allow_mpp-new-in-v50) and [`tidb_enforce_mpp`](/system-variables.md#tidb_enforce_mpp-new-in-v51).

+
+The `tidb_allow_mpp` variable controls whether TiDB can select the MPP mode to execute queries. The `tidb_enforce_mpp` variable controls whether the optimizer's cost estimation is ignored and the MPP mode of TiFlash is forcibly used to execute queries.
+
+The results corresponding to all values of these two variables are as follows:
+
+| | tidb_allow_mpp=off | tidb_allow_mpp=on (by default) |
+| ---------------------- | -------------------- | -------------------------------- |

+| tidb_enforce_mpp=on | The MPP mode is not used. | TiDB ignores the cost estimation and selects the MPP mode. |
+
+For example, if you do not want to use the MPP mode, you can execute the following statements:

-MPP mode supports these physical algorithms: Broadcast Hash Join, Shuffled Hash Join, Shuffled Hash Aggregation, Union All, TopN, and Limit. The optimizer automatically determines which algorithm to be used in a query. To check the specific query execution plan, you can execute the `EXPLAIN` statement. If the result of the `EXPLAIN` statement shows ExchangeSender and ExchangeReceiver operators, it indicates that the MPP mode has taken effect.

In the example above, `a/b`'s inferred type from the compiling is `Decimal(7,4)` both in TiDB and in TiFlash. Constrained by `Decimal(7,4)`, `a/b`'s returned type should be `0.0000`.

+# DATA_LOCK_WAITS
+
+The `DATA_LOCK_WAITS` table shows the ongoing pessimistic locks waiting on all TiKV nodes in the cluster.
+
+> **Warning:**
+>
+> Currently, this is an experimental feature. The definition and behavior of the table structure might have major changes in future releases.
+
+{{< copyable "sql" >}}
+
+```sql
+USE information_schema;
+DESC data_lock_waits;
+```
+
+```sql
++------------------------+---------------------+------+------+---------+-------+
+| Field | Type | Null | Key | Default | Extra |
++------------------------+---------------------+------+------+---------+-------+
+| KEY | varchar(64) | NO | | NULL | |
+| TRX_ID | bigint(21) unsigned | NO | | NULL | |
+| CURRENT_HOLDING_TRX_ID | bigint(21) unsigned | NO | | NULL | |
+| SQL_DIGEST | varchar(64) | YES | | NULL | |
++------------------------+---------------------+------+------+---------+-------+
+```
+
+The meaning of each column field in the `DATA_LOCK_WAITS` table is as follows:
+
+* `KEY`: The KEY that is waiting for the lock and displayed in the form of hexadecimal string.
+* `TRX_ID`: The ID of the transaction that is waiting for the lock. This ID is also the `start_ts` of the transaction.
+* `CURRENT_HOLDING_TRX_ID`: The ID of the transaction that currently holds the lock. This ID is also the `start_ts` of the transaction.
+* `SQL_DIGEST`: The digest of the SQL statement that is currently blocked in the lock-waiting transaction.
+
+> **Warning:**
+>
+> * The information in this table is obtained in real time from all TiKV nodes during the query. Currently, even if the `WHERE` condition is added, TiDB might still collect information from all TiKV nodes. If the cluster is large and the load is high, querying this table might cause a potential risk of performance jitter. Therefore, use this table according to your actual situation.
+> * The information from different TiKV nodes is NOT guaranteed to be the snapshot at the same point in time.
+
+## Example
+
+{{< copyable "sql" >}}
+
+```sql
+select * from information_schema.data_lock_waits\G
+```
+
+```sql
+*************************** 1. row ***************************

+2 rows in set (0.01 sec)
+```
+
+The above query result shows that the transaction of the ID `425405024158875649` was trying to obtain the pessimistic lock on the key `7480000000000000355f728000000000000002` when the statement with digest `"f7530877a35ae65300c42250abd8bc731bbaf0a7cabc05dab843565230611bb22"` was being executed, but the lock on this key was held by the transaction of the ID `425405016242126849`.
+
+## SQL Digest
+
+The `DATA_LOCK_WAITS` table records the SQL digest but not the original SQL statement.
+
+SQL digest is the hash value of the normalized SQL statement. To find the original SQL statement corresponding to the SQL digest, perform one of the following operations:
+
+- For the statements executed on the current TiDB node in the recent period of time, you can find the corresponding original SQL statement in the `STATEMENTS_SUMMARY` or `STATEMENTS_SUMMARY_HISTORY` table according to the SQL digest.
+- For the statements executed on all TiDB nodes in the entire cluster in the recent period of time, you can find the corresponding SQL statement in the `CLUSTER_STATEMENTS_SUMMARY` or `CLUSTER_STATEMENTS_SUMMARY_HISTORY` table according to the SQL digest.
+
+{{< copyable "sql" >}}
+
+```sql
+select digest, digest_text from information_schema.statements_summary where digest = "f7530877a35ae65300c42250abd8bc731bbaf0a7cabc05dab843565230611bb2";
+```

+# DEADLOCKS
+
+The `DEADLOCKS` table shows the information of the several deadlock errors that have occurred recently on the current TiDB node.
+
+> **Warning:**
+>
+> Currently, this is an experimental feature. The definition and behavior of the table structure might have major changes in future releases.
+
+{{< copyable "sql" >}}
+
+```sql
+USE information_schema;
+DESC deadlocks;
+```
+
+```sql
++--------------------+---------------------+------+------+---------+-------+
+| Field | Type | Null | Key | Default | Extra |
++--------------------+---------------------+------+------+---------+-------+
+| DEADLOCK_ID | bigint(21) | NO | | NULL | |

++--------------------+---------------------+------+------+---------+-------+
+```
+
+The `DEADLOCKS` table uses multiple rows to show the same deadlock event, and each row displays the information about one of the transactions involved in the deadlock event. If the TiDB node records multiple deadlock errors, each error is distinguished using the `DEADLOCK_ID` column. The same `DEADLOCK_ID` indicates the same deadlock event. Note that `DEADLOCK_ID` **does not guarantee global uniqueness and will not be persisted**. It only shows the same deadlock event in the same result set.
+
+The meaning of each column field in the `DEADLOCKS` table is as follows:
+
+* `DEADLOCK_ID`: The ID of the deadlock event. When multiple deadlock errors exist in the table, you can use this column to distinguish rows that belong to different deadlock errors.
+* `OCCUR_TIME`: The time when the deadlock error occurs.
+* `RETRYABLE`: Whether the deadlock error can be retried. Currently, TiDB does not support collecting the information of the retryable deadlock error, so the value of this field is always `0`. For the description of retryable deadlock errors, see the [Retryable deadlock errors](#retryable-deadlock-errors) section.
+* `TRY_LOCK_TRX_ID`: The ID of the transaction that tries to acquire lock. This ID is also the `start_ts` of the transaction.
+* `CURRENT_SQL_DIGEST`: The digest of the SQL statement currently being executed in the lock-acquiring transaction.
+* `KEY`: The blocked key that the transaction tries to lock. The value of this field is displayed in the form of hexadecimal string.
+* `TRX_HOLDING_LOCK`: The ID of the transaction that currently holds the lock on the key and causes blocking. This ID is also the `start_ts` of the transaction.
+
+To adjust the maximum number of deadlock events that can be recorded in the `DEADLOCKS` table, adjust the [`pessimistic-txn.deadlock-history-capacity`](/tidb-configuration-file.md#deadlock-history-capacity) configuration in the TiDB configuration file. By default, the information of the recent 10 deadlock events is recorded in the table.
+
+## Example 1
+
+Assume that the table definition and the initial data are as follows:
+
+{{< copyable "sql" >}}
+
+```sql
+create table t (id int primary key, v int);
+insert into t values (1, 10), (2, 20);
+```
+
+Execute the two transactions in the following order:
+
+| Transaction 1 | Transaction 2 | Description |
+|--------------------------------------|--------------------------------------|----------------------|
+| `update t set v = 11 where id = 1;` | | |
+| | `update t set v = 21 where id = 2;` | |
+| `update t set v = 12 where id = 2;` | | Transaction 1 gets blocked. |
+| | `update t set v = 22 where id = 1;` | Transaction 2 reports a deadlock error. |
+
+Next, transaction 2 reports a deadlock error. At this time, query the `DEADLOCKS` table:
+
+{{< copyable "sql" >}}
+
+```sql
+select * from information_schema.deadlocks;
+```
+
+The expected output is as follows:
+
+```sql
++-------------+----------------------------+-----------+--------------------+------------------------------------------------------------------+----------------------------------------+--------------------+
+| DEADLOCK_ID | OCCUR_TIME | RETRYABLE | TRY_LOCK_TRX_ID | CURRENT_SQL_DIGEST | KEY | TRX_HOLDING_LOCK |
++-------------+----------------------------+-----------+--------------------+------------------------------------------------------------------+----------------------------------------+--------------------+
+| 1 | 2021-06-04 08:22:38.765699 | 0 | 425405959304904707 | 22230766411edb40f27a68dadefc63c6c6970d5827f1e5e22fc97be2c4d8350d | 7480000000000000385F728000000000000002 | 425405959304904708 |
+| 1 | 2021-06-04 08:22:38.765699 | 0 | 425405959304904708 | 22230766411edb40f27a68dadefc63c6c6970d5827f1e5e22fc97be2c4d8350d | 7480000000000000385F728000000000000001 | 425405959304904707 |
++-------------+----------------------------+-----------+--------------------+------------------------------------------------------------------+----------------------------------------+--------------------+
+```
+
+Two rows of data are generated in the `DEADLOCKS` table. The `DEADLOCK_ID` field of both rows is `1`, which means that the information in both rows belongs to the same deadlock error. The first row shows that the transaction of the ID `425405959304904707` is blocked on the key of `"7480000000000000385F728000000000000002"` by the transaction of the ID `"425405959304904708"`. The second row shows that the transaction of the ID `"425405959304904708"` is blocked on the key of `"7480000000000000385F728000000000000001"` by the transaction of the ID `425405959304904707`, which constitutes mutual blocking and forms a deadlock.
+
+## Example 2
+
+Assume that you query the `DEADLOCKS` table and get the following result:
+
+```sql
++-------------+----------------------------+-----------+--------------------+------------------------------------------------------------------+----------------------------------------+--------------------+
+| DEADLOCK_ID | OCCUR_TIME | RETRYABLE | TRY_LOCK_TRX_ID | CURRENT_SQL_DIGEST | KEY | TRX_HOLDING_LOCK |
++-------------+----------------------------+-----------+--------------------+------------------------------------------------------------------+----------------------------------------+--------------------+
+| 1 | 2021-06-04 08:22:38.765699 | 0 | 425405959304904707 | 22230766411edb40f27a68dadefc63c6c6970d5827f1e5e22fc97be2c4d8350d | 7480000000000000385F728000000000000002 | 425405959304904708 |

+| 2 | 2021-06-04 08:22:56.795410 | 0 | 425405961664462853 | 22230766411edb40f27a68dadefc63c6c6970d5827f1e5e22fc97be2c4d8350d | 7480000000000000385F728000000000000002 | 425405961664462854 |
+| 2 | 2021-06-04 08:22:56.795410 | 0 | 425405961664462854 | 22230766411edb40f27a68dadefc63c6c6970d5827f1e5e22fc97be2c4d8350d | 7480000000000000385F728000000000000003 | 425405961664462855 |
+| 2 | 2021-06-04 08:22:56.795410 | 0 | 425405961664462855 | 22230766411edb40f27a68dadefc63c6c6970d5827f1e5e22fc97be2c4d8350d | 7480000000000000385F728000000000000001 | 425405961664462853 |
++-------------+----------------------------+-----------+--------------------+------------------------------------------------------------------+----------------------------------------+--------------------+
+```
+
+The `DEADLOCK_ID` column in the above query result shows that the first two rows together represent the information of a deadlock error, and the two transactions that wait for each other form the deadlock. The next three rows together represent another deadlock information, and the three transactions that wait in a cycle form the deadlock.
+
+## Retryable deadlock errors
+
+> **Note:**
+>
+> Currently, TiDB does not support collecting retryable deadlock errors in the `DEADLOCKS` table.
+
+When transaction A is blocked by a lock already held by transaction B, and transaction B is directly or indirectly blocked by the lock held by the current transaction A, a deadlock error will occur. In this deadlock, there might be two cases:
+
++ Case 1: Transaction B might be (directly or indirectly) blocked by a lock generated by a statement that has been executed after transaction A starts and before transaction A gets blocked.
++ Case 2: Transaction B might also be blocked by the statement currently being executed in transaction A.
+
+In case 1, TiDB will report a deadlock error to the client of transaction A and terminate the transaction.
+
+In case 2, the statement currently being executed in transaction A will be automatically retried in TiDB. For example, suppose that transaction A executes the following statement:
+
+{{< copyable "sql" >}}
+
+```sql
+update t set v = v + 1 where id = 1 or id = 2;
+```
+
+Transaction B executes the following two statements successively.
+
+{{< copyable "sql" >}}
+
+```sql
+update t set v = 4 where id = 2;
+update t set v = 2 where id = 1;
+```
+
+Then if transaction A locks the two rows with `id = 1` and `id = 2`, and the two transactions run in the following sequence:
+
+1. Transaction A locks the row with `id = 1`.
+2. Transaction B executes the first statement and locks the row with `id = 2`.
+3. Transaction B executes the second statement and tries to lock the row with `id = 1`, which is blocked by transaction A.
+4. Transaction A tries to lock the row with `id = 2` and is blocked by transaction B, which forms a deadlock.
+
+For this case, because the statement of transaction A that blocks other transactions is also the statement currently being executed, the pessimistic lock on the current statement can be resolved (so that transaction B can continue to run), and the current statement can be retried. TiDB uses the key hash internally to determine whether this is the case.
+
+When a retryable deadlock occurs, the internal automatic retry will not cause a transaction error, so it is transparent to the client. However, if this situation occurs frequently, the performance might be affected. When this occurs, you can see `single statement deadlock, retry statement` in the TiDB log.
+
+## CLUSTER_DEADLOCKS
+
+The `CLUSTER_DEADLOCKS` table returns information about the recent deadlock errors on each TiDB node in the entire cluster, which is the information of the `DEADLOCKS` table on each node combined together. `CLUSTER_DEADLOCKS` also contains an additional `INSTANCE` column to display the IP address and port of the node to distinguish between different TiDB nodes.
+
+Note that, because `DEADLOCK_ID` does not guarantee global uniqueness, in the query result of the `CLUSTER_DEADLOCKS` table, you need to use the `INSTANCE` and `DEADLOCK_ID` together to distinguish the information of different deadlock errors in the result set.
+
+{{< copyable "sql" >}}
+
+```sql
+USE information_schema;
+DESC cluster_deadlocks;
+```
+
+```sql
++--------------------+---------------------+------+------+---------+-------+
+| Field | Type | Null | Key | Default | Extra |
++--------------------+---------------------+------+------+---------+-------+
+| INSTANCE | varchar(64) | YES | | NULL | |
+| DEADLOCK_ID | bigint(21) | NO | | NULL | |
+| OCCUR_TIME | timestamp(6) | YES | | NULL | |
+| RETRYABLE | tinyint(1) | NO | | NULL | |
+| TRY_LOCK_TRX_ID | bigint(21) unsigned | NO | | NULL | |
+| CURRENT_SQL_DIGEST | varchar(64) | YES | | NULL | |
+| KEY | text | YES | | NULL | |
+| TRX_HOLDING_LOCK | bigint(21) unsigned | NO | | NULL | |
++--------------------+---------------------+------+------+---------+-------+
+```
+
+## SQL Digest
+
+The `DEADLOCKS` table records the SQL digest but not the original SQL statement.
+
+SQL digest is the hash value after the SQL normalization. To find the original SQL statement corresponding to the SQL digest, perform one of the following operations:
+
+- For the statements executed on the current TiDB node in the recent period of time, you can find the corresponding original SQL statement in the `STATEMENTS_SUMMARY` or `STATEMENTS_SUMMARY_HISTORY` table according to the SQL digest.
+- For the statements executed on all TiDB nodes in the entire cluster in the recent period of time, you can find the corresponding SQL statement in the `CLUSTER_STATEMENTS_SUMMARY` or `CLUSTER_STATEMENTS_SUMMARY_HISTORY` table according to the SQL digest.
+
+{{< copyable "sql" >}}
+
+```sql
+select digest, digest_text from information_schema.statements_summary where digest = "f7530877a35ae65300c42250abd8bc731bbaf0a7cabc05dab843565230611bb2";
+```
+
+```sql
++------------------------------------------------------------------+---------------------------------------+

++------------------------------------------------------------------+---------------------------------------+
+```

+
+The meaning of each column field in the `TIDB_TRX` table is as follows:
+
+* `ID`: The transaction ID, which is the `start_ts` (start timestamp) of the transaction.
+* `START_TIME`: The start time of the transaction, which is the physical time corresponding to the `start_ts` of the transaction.
+* `CURRENT_SQL_DIGEST`: The digest of the SQL statement currently being executed in the transaction.
+* `STATE`: The current state of the transaction. The possible values include:
+ * `Normal`: The transaction is being executed normally or in an idle state.
+ * `LockWaiting`: The transaction is waiting for the pessimistic lock to be acquired. Note that the transaction enters this state at the beginning of the pessimistic locking operation, no matter whether it is blocked by other transactions or not.
+ * `Committing`: The transaction is in the process of commit.
+ * `RollingBack`: The transaction is being rolled back.
+* `WAITING_START_TIME`: When the value of `STATE` is `LockWaiting`, this column shows the start time of the waiting.
+* `MEM_BUFFER_KEYS`: The number of keys written into the memory buffer by the current transaction.
+* `MEM_BUFFER_BYTES`: The total number of key-value bytes written into the memory buffer by the current transaction.
+* `SESSION_ID`: The ID of the session to which this transaction belongs.
+* `USER`: The name of the user who performs the transaction.
+* `DB`: The current default database name of the session in which the transaction is executed.
+* `ALL_SQL_DIGESTS`: The digest list of statements that have been executed in this transaction. For each transaction, the first 50 statements at most are recorded.
+
+## Example
+
+{{< copyable "sql" >}}
+
+```sql
+select * from information_schema.tidb_trx\G
+```
+
+```sql
+*************************** 1. row ***************************
+ ID: 425403705115541506
+ START_TIME: 2021-06-04 05:59:10.691000
+CURRENT_SQL_DIGEST: NULL
+ STATE: Normal
+WAITING_START_TIME: NULL
+ MEM_BUFFER_KEYS: 2
+ MEM_BUFFER_BYTES: 48
+ SESSION_ID: 7
+ USER: root
+ DB: test
+ ALL_SQL_DIGESTS: [e6f07d43b5c21db0fbb9a31feac2dc599787763393dd5acbfad80e247eb02ad5, 04fa858fa491c62d194faec2ab427261cc7998b3f1ccf8f6844febca504cb5e9, f7530877a35ae65300c42250abd8bc731bbaf0a7cabc05dab843565230611bb2]
+1 row in set (0.00 sec)
+```
+
+The query result of the above example indicates that a transaction is being executed on the current node (the `STATE` is `Normal`), and this transaction is currently idle (`CURRENT_SQL_DIGEST` is `NULL`). This transaction has executed three statements (there are three records in the `ALL_SQL_DIGESTS` list and they are the digests of the three executed statements).
+
+## CLUSTER_TIDB_TRX
+
+The `TIDB_TRX` table only provides information about the transactions that are being executed on a single TiDB node. If you want to view the information of the transactions that are being executed on all TiDB nodes in the entire cluster, you need to query the `CLUSTER_TIDB_TRX` table. Compared with the query result of the `TIDB_TRX` table, the query result of the `CLUSTER_TIDB_TRX` table contains an extra `INSTANCE` field.

+## SQL Digest
+
+The `TIDB_TRX` table only records SQL digests, not the original SQL statement.
+
+SQL digest is the hash value after the SQL normalization. To find the original SQL statement corresponding to the SQL digest, perform one of the following operations:
+
+- For the statements executed on the current TiDB node in the recent period of time, you can find the corresponding orginal SQL statement from the SQL digest in `STATEMENTS_SUMMARY` or `STATEMENTS_SUMMARY_HISTORY`.
+- For the statements executed on all TiDB nodes in the entire cluster in the recent period of time, you can find the corresponding SQL statement from the SQL digest in `CLUSTER_STATEMENTS_SUMMARY` or `CLUSTER_STATEMENTS_SUMMARY_HISTORY`.
+
+{{< copyable "sql" >}}
+
+```sql
+select digest, digest_text from information_schema.statements_summary where digest = "f7530877a35ae65300c42250abd8bc731bbaf0a7cabc05dab843565230611bb2";
+```

The transaction execution time can not exceed the GC time limit. In addition, the TTL time of pessimistic transactions has an upper limit, whose default value is 1 hour. Therefore, a pessimistic transaction executed for more than 1 hour will fail to commit. This timeout threshold is controlled by the TiDB parameter [performance.max-txn-ttl](https://github.com/pingcap/tidb/blob/master/config/config.toml.example).

+
+### Use Lock View to troubleshoot issues related to pessimistic locks
+
+Since v5.1, TiDB supports the Lock View feature. This feature has several system tables built in `information_schema` that provide more information about the pessimistic lock conflicts and pessimistic lock waitings. For the detailed introduction of these tables, see the following documents:
+
+* [`TIDB_TRX` and `CLUSTER_TIDB_TRX`](/information-schema/information-schema-tidb-trx.md): Provides information of all running transactions on the current TiDB node or in the entire cluster, including whether the transaction is in the lock-waiting state, the lock-waiting time, and the digests of statements that have been executed in the transaction.
+* [`DATA_LOCK_WAITS`](/information-schema/information-schema-data-lock-waits.md): Provides the pessimistic lock-waiting information in TiKV, including the `start_ts` of the blocking and blocked transaction, the digest of the blocked SQL statement, and the key on which the waiting occurs.
+* [`DEADLOCKS` and `CLUSTER_DEADLOCKS`](/information-schema/information-schema-deadlocks.md): Provides the information of several deadlock events that have recently occurred on the current TiDB node or in the entire cluster, including the waiting relationship among transactions in the deadlock loops, the digest of the statement currently being executed in the transaction, and the key on which the waiting occurs.
+
+> **Warning:**
+>
+> Currently, this is an experimental feature. The definition and behavior of the table structure might have major changes in future releases.
+
+The following sections show the examples of troubleshooting some issues using these tables.
+
+#### Deadlock errors
+
+To get the information of the recent deadlock errors, you can query the `DEADLOCKS` or `CLUSTER_DEADLOCKS` table. For example:
+
+{{< copyable "sql" >}}
+
+```sql
+select * from information_schema.deadlocks;
+```
+
+```sql
++-------------+----------------------------+-----------+--------------------+------------------------------------------------------------------+----------------------------------------+--------------------+

++-------------+----------------------------+-----------+--------------------+------------------------------------------------------------------+----------------------------------------+--------------------+
+```
+
+The query result above shows the waiting relationship among multiple transactions in the deadlock error, the digest of the SQL statement currently being executed in each transaction, and the key on which the conflict occurs.
+
+You can get the text of the normalized SQL statement corresponding to the digest of the SQL statements executed recently from the `STATEMENTS_SUMMARY` or `STATEMENTS_SUMMARY_HISTORY` table. For details, see [`STATEMENTS_SUMMARY` and `STATEMENTS_SUMMARY_HISTORY` tables](/statement-summary-tables.md). You can also join the obtained results directly with the `DEADLOCKS` table. Note that the `STATEMENTS_SUMMARY` table might not contain the information of all SQL statements, so left join is used in the following example:
+
+{{< copyable "sql" >}}
+
+```sql
+select l.deadlock_id, l.occur_time, l.try_lock_trx_id, l.trx_holding_lock, s.digest_text from information_schema.deadlocks as l left join information_schema.statements_summary as s on l.current_sql_digest = s.digest;
+```
+
+```sql
++-------------+----------------------------+--------------------+--------------------+-----------------------------------------+
+| deadlock_id | occur_time | try_lock_trx_id | trx_holding_lock | digest_text |
++-------------+----------------------------+--------------------+--------------------+-----------------------------------------+
+| 1 | 2021-06-04 08:22:38.765699 | 425405959304904707 | 425405959304904708 | update `t` set `v` = ? where `id` = ? ; |
+| 1 | 2021-06-04 08:22:38.765699 | 425405959304904708 | 425405959304904707 | update `t` set `v` = ? where `id` = ? ; |
++-------------+----------------------------+--------------------+--------------------+-----------------------------------------+
+```
+
+#### A few hot keys cause queueing locks
+
+The `DATA_LOCK_WAITS` system table provides the lock-waiting status on the TiKV nodes. When you query this table, TiDB automatically obtains the real-time lock-waiting information from all TiKV nodes. If a few hot keys are frequently locked and block many transactions, you can query the `DATA_LOCK_WAITS` table and aggregate the results by key to try to find the keys on which issues frequently occur:
+
+{{< copyable "sql" >}}
+
+```sql
+select `key`, count(*) as `count` from information_schema.data_lock_waits group by `key` order by `count` desc;
+```
+
+```sql
++----------------------------------------+-------+
+| key | count |
++----------------------------------------+-------+
+| 7480000000000000415f728000000000000001 | 2 |
+| 7480000000000000415f728000000000000002 | 1 |
++----------------------------------------+-------+
+```
+
+To avoid contingency, you might need to make multiple queries.
+
+If you know the key that frequently has issues occurred, you can try to get the information of the transaction that tries to lock the key from the `TIDB_TRX` or `CLUSTER_TIDB_TRX` table.
+
+Note that the information displayed in the `TIDB_TRX` and `CLUSTER_TIDB_TRX` tables is also the information of the transactions that are running at the time the query is performed. These tables do not display the information of the completed transactions. If there is a large number of concurrent transactions, the result set of the query might also be large. You can use the `limit` clause or the `where` clause to filter out transactions with a long lock-waiting time. Note that when you join multiple tables in Lock View, the data in different tables might not be obtained at the same time, so the information in different tables might not be consistent.
+
+{{< copyable "sql" >}}
+
+```sql
+select trx.* from information_schema.data_lock_waits as l left join information_schema.tidb_trx as trx on l.trx_id = trx.id where l.key = "7480000000000000415f728000000000000001"\G

+# Read Historical Data Using the `AS OF TIMESTAMP` Clause
+
+This document describes how to perform the [Stale Read](/stale-read.md) feature using the `AS OF TIMESTAMP` clause to read historical data in TiDB, including specific usage examples and strategies for saving historical data.
+
+TiDB supports reading historical data through a standard SQL interface, which is the `AS OF TIMESTAMP` SQL clause, without the need for special clients or drivers. After data is updated or deleted, you can read the historical data before the update or deletion using this SQL interface.
+
+> **Note:**
+>
+> When reading historical data, TiDB returns the data with the old table structure even if the current table structure is different.
+
+## Syntax
+
+You can use the `AS OF TIMESTAMP` clause in the following three ways:
+
+- [`SELECT ... FROM ... AS OF TIMESTAMP`](/sql-statements/sql-statement-select.md)
+- [`START TRANSACTION READ ONLY AS OF TIMESTAMP`](/sql-statements/sql-statement-start-transaction.md)
+- [`SET TRANSACTION READ ONLY AS OF TIMESTAMP`](/sql-statements/sql-statement-set-transaction.md)
+
+If you want to specify an exact point of time, you can set a datetime value or use a time function in the `AS OF TIMESTAMP` clause. The format of datetime is like "2016-10-08 16:45:26.999", with millisecond as the minimum time unit, but for most of the time, the time unit of second is enough for specifying a datetime, such as "2016-10-08 16:45:26". You can also get the current time to the millisecond using the `NOW(3)` function. If you want to read the data of several seconds ago, it is **recommended** to use an expression such as `NOW() - INTERVAL 10 SECOND`.
+
+If you want to specify a time range, you can use the `TIDB_BOUNDED_STALENESS()` function in the clause. When this function is used, TiDB selects a suitable timestamp within the specified time range. "Suitable" means there are no transactions that start before this timestamp and have not been committed on the accessed replica, that is, TiDB can perform read operations on the accessed replica and the read operations are not blocked. You need to use `TIDB_BOUNDED_STALENESS(t1, t2)` to call this function. `t1` and `t2` are the two ends of the time range, which can be specified using either datetime values or time functions.
+
+Here are some examples of the `AS OF TIMESTAMP` clause:
+
+- `AS OF TIMESTAMP '2016-10-08 16:45:26'`: Tells TiDB to read the latest data stored at 16:45:26 on October 8, 2016.
+- `AS OF TIMESTAMP NOW() - INTERVAL 10 SECOND`: Tells TiDB to read the latest data stored 10 seconds ago.
+- `AS OF TIMESTAMP TIDB_BOUNDED_STALENESS('2016-10-08 16:45:26', '2016-10-08 16:45:29')`: Tells TiDB to read the data as new as possible within the time range of 16:45:26 to 16:45:29 on October 8, 2016.
+- `AS OF TIMESTAMP TIDB_BOUNDED_STALENESS(NOW() - INTERVAL 20 SECOND, NOW())`: Tells TiDB to read the data as new as possible within the time range of 20 seconds ago to the present.
+
+Note that in addition to specifying a timestamp, the most common use of the `AS OF TIMESTAMP` clause is to read data that is several seconds old. If this approach is used, it is recommended to read historical data older than 5 seconds.
+
+## Usage examples
+
+This section describes different ways to use the `AS OF TIMESTAMP` clause with several examples. It first introduces how to prepare the data for recovery, and then shows how to use `AS OF TIMESTAMP` in `SELECT`, `START TRANSACTION READ ONLY AS OF TIMESTAMP`, and `SET TRANSACTION READ ONLY AS OF TIMESTAMP` respectively.
+
+### Prepare data sample
+
+To prepare data for recovery, create a table first and insert several rows of data:
+
+```sql
+create table t (c int);
+```
+
+```
+Query OK, 0 rows affected (0.01 sec)
+```
+
+```sql
+insert into t values (1), (2), (3);
+```
+
+```
+Query OK, 3 rows affected (0.00 sec)
+```
+
+View the data in the table:
+
+```sql
+select * from t;
+```
+
+```
++------+
+| c |
++------+
+| 1 |
+| 2 |
+| 3 |
++------+
+3 rows in set (0.00 sec)
+```
+
+View the current time:
+
+```sql
+select now();
+```
+
+```
++---------------------+
+| now() |
++---------------------+
+| 2021-05-26 16:45:26 |
++---------------------+
+1 row in set (0.00 sec)
+```
+
+Update the data in a row:
+
+```sql
+update t set c=22 where c=2;
+```
+
+```
+Query OK, 1 row affected (0.00 sec)
+```
+
+Confirm that the data of the row is updated:
+
+```sql
+select * from t;
+```
+
+```
++------+
+| c |
++------+
+| 1 |
+| 22 |
+| 3 |
++------+
+3 rows in set (0.00 sec)
+```
+
+### Read historical data using the `SELECT` statement
+
+You can use the [`SELECT ... FROM ... AS OF TIMESTAMP`](/sql-statements/sql-statement-select.md) statement to read data from a time point in the past.
+
+```sql
+select * from t as of timestamp '2021-05-26 16:45:26';
+```
+
+```
++------+
+| c |
++------+
+| 1 |
+| 2 |
+| 3 |
++------+
+3 rows in set (0.00 sec)
+```
+
+> **Note:**
+>
+> When reading multiple tables using one `SELECT` statement, you need to make sure that the format of TIMESTAMP EXPRESSIONs is consistent. For example, `select * from t as of timestamp NOW() - INTERVAL 2 SECOND, c as of timestamp NOW() - INTERVAL 2 SECOND;`. In addition, you must specify the `AS OF` information for the relevant table in the `SELECT` statement; otherwise, the `SELECT` statement reads the latest data by default.
+
+### Read historical data using the `START TRANSACTION READ ONLY AS OF TIMESTAMP` statement
+
+You can use the [`START TRANSACTION READ ONLY AS OF TIMESTAMP`](/sql-statements/sql-statement-start-transaction.md) statement to start a read-only transaction based on a time point in the past. The transaction reads historical data of the given time.
+
+```sql
+start transaction read only as of timestamp '2021-05-26 16:45:26';
+```
+
+```
+Query OK, 0 rows affected (0.00 sec)
+```
+
+```sql
+select * from t;
+```
+
+```
++------+
+| c |
++------+
+| 1 |
+| 2 |
+| 3 |
++------+
+3 rows in set (0.00 sec)
+```
+
+```sql
+commit;
+```
+
+```
+Query OK, 0 rows affected (0.00 sec)
+```
+
+After the transaction is committed, you can read the latest data.
+
+```sql
+select * from t;
+```
+
+```
++------+
+| c |
++------+
+| 1 |
+| 22 |
+| 3 |
++------+
+3 rows in set (0.00 sec)
+```
+
+> **Note:**
+>
+> If you start a transaction with the statement `START TRANSACTION READ ONLY AS OF TIMESTAMP`, it is a read-only transaction. Write operations are rejected in this transaction.
+
+### Read historical data using the `SET TRANSACTION READ ONLY AS OF TIMESTAMP` statement
+
+You can use the [`SET TRANSACTION READ ONLY AS OF TIMESTAMP`](/sql-statements/sql-statement-set-transaction.md) statement to set the next transaction as a read-only transaction based on a specified time point in the past. The transaction reads historical data of the given time.
+
+```sql
+set transaction read only as of timestamp '2021-05-26 16:45:26';
+```
+
+```
+Query OK, 0 rows affected (0.00 sec)
+```
+
+```sql
+begin;
+```
+
+```
+Query OK, 0 rows affected (0.00 sec)
+```
+
+```sql
+select * from t;
+```
+
+```
++------+
+| c |
++------+
+| 1 |
+| 2 |
+| 3 |
++------+
+3 rows in set (0.00 sec)
+```
+
+```sql
+commit;
+```
+
+```
+Query OK, 0 rows affected (0.00 sec)
+```
+
+After the transaction is committed, you can read the latest data.
+
+```sql
+select * from t;
+```
+
+```
++------+
+| c |
++------+
+| 1 |
+| 22 |
+| 3 |
++------+
+3 rows in set (0.00 sec)
+```
+
+> **Note:**
+>
+> If you start a transaction with the statement `SET TRANSACTION READ ONLY AS OF TIMESTAMP`, it is a read-only transaction. Write operations are rejected in this transaction.

+title: Local Read under Three Data Centers Deployment
+summary: Learn how to use the Stale Read feature to read local data under three DCs deployment and thus reduce cross-center requests.
+---
+
+# Local Read under Three Data Centers Deployment
+
+In the model of three data centers, a Region has three replicas which are isolated in each data center. However, due to the requirement of strongly consistent read, TiDB must access the Leader replica of the corresponding data for every query. If the query is generated in a data center different from that of the Leader replica, TiDB needs to read data from another data center, thus causing the access latency to increase.
+
+This document describes how to use the [Stale Read](/stale-read.md) feature to avoid cross-center access and reduce the access latency at the expense of real-time data availability.
+
+## Deploy a TiDB cluster of three data centers
+
+For the three-data-center deployment method, refer to [Multiple Data Centers in One City Deployment](/multi-data-centers-in-one-city-deployment.md).
+
+Note that if both the TiKV and TiDB nodes have the configuration item `labels` configured, the TiKV and TiDB nodes in the same data center must have the same value for the `zone` label. For example, if a TiKV node and a TiDB node are both in the data center `dc-1`, then the two nodes need to be configured with the following label:
+
+```
+[labels]
+zone=dc-1
+```
+
+## Perform local read using Stale Read
+
+[Stale Read](/stale-read.md) is a mechanism that TiDB provides for the users to read historical data. Using this mechanism, you can read the corresponding historical data of a specific point in time or within a specified time range, and thus save the latency brought by data replication between storage nodes. When using Stale Read in some scenarios of geo-distributed deployment, TiDB accesses the replica in the current data center to read the corresponding data at the expense of some real-time performance, which avoids network latency brought by cross-center connection and reduces the access latency for the entire query process.
+
+When TiDB receives a Stale Read query, if the `zone` label of that TiDB node is configured, then TiDB sends the request to the TiKV node with the same `zone` label where the corresponding data replica resides.
+
+For how to perform Stale Read, see [Perform Stale Read using the `AS OF TIMESTAMP` clause](/as-of-timestamp.md).

+---
+
+# Usage Scenarios of Stale Read
+
+This document describes the usage scenarios of Stale Read. Stale Read is a mechanism that TiDB applies to read historical versions of data stored in TiDB. Using this mechanism, you can read the corresponding historical data of a specific point in time or within a specified time range, and thus save the latency brought by data replication between storage nodes.
+
+In terms of the internal implementation, Stale Read allows TiDB to read from any replica the data of the specified point in time or the data as new as possible within the specified time range, and to always ensure the data consistency constraint during the reading process.
+
+## Scenario examples
+
++ Scenario one: If a transaction only involves read operations and is tolerant of data staleness to some extent, you can use Stale Read to get historical data. Using Stale Read, TiDB sends the query requests to any replica of the corresponding data at the expense of some real-time performance, and thus increases the throughput of query executions.
+
++ Scenario two: In some scenarios where small tables are queried, if strongly consistent reads are used, data might be concentrated on a certain storage node, causing the query pressure to be concentrated on that node as well. Therefore, that node might become a bottleneck for the whole query. With Stale Read, TiDB distributes the query requests to each replica of the corresponding data, which can improve the overall query throughput and significantly improve the query performance.
+
++ Scenario three: In some scenarios of geo-distributed deployment, if strongly consistent follower reads are used, to make sure that the data read from the Followers is consistent with that stored in the Leader, TiDB requests `Readindex` from different data centers for verification, which increases the access latency for the whole query process. With Stale Read, TiDB accesses the replica in the current data center to read the corresponding data at the expense of some real-time performance, which avoids network latency brought by cross-center connection and reduces the access latency for the entire query. For more information, see [Local Read under Three Data Centers Deployment](/best-practices/three-dc-local-read.md).
+
+## Usages
+
+In TiDB, you can specify either an exact point in time or a time range when performing stale reads:
+
+- Specifying an exact point in time (recommended): If you need TiDB to read data that follows the global transaction consistency from a specific point in time without damaging the isolation level, you can specify the corresponding timestamp of that point in time in the query statement. For detailed usage, see [`AS OF TIMESTAMP` Clause](/as-of-timestamp.md#syntax).
+- Specifying a time range: If you need TiDB to read data as new as possible within a time range without damaging the isolation level, you can specify the time range in the query statement. Then, TiDB selects a suitable timestamp within the specified time range to read the corresponding data. "Suitable" means there are no transactions that start before this timestamp and have not been committed on the accessed replica, that is, TiDB can perform read operations on the accessed replica and the read operations are not blocked. For detailed usage, refer to the introduction of the [`AS OF TIMESTAMP` clause](/as-of-timestamp.md#syntax) and the [`TIDB_BOUNDED_STALENESS` function](/as-of-timestamp.md#syntax).

-# TiDB Docker Compose Deployment
-
-> **Warning:**
->
-> The Docker Compose deployment method provided in this document is no longer maintained. If you want to test TiDB, it is recommended to refer to [Quick Start Guide for the TiDB Database Platform](/quick-start-with-tidb.md) for deployment. For **production environment**, **do not use** Docker Compose for deployment, but [deploy TiDB with TiUP](/production-deployment-using-tiup.md) or [TiDB Operator in Kubernetes](https://docs.pingcap.com/tidb-in-kubernetes/stable/deploy-tidb-operator).
-
-This document describes how to quickly deploy a TiDB testing cluster with a single command using [Docker Compose](https://docs.docker.com/compose/overview).
-
-With Docker Compose, you can use a YAML file to configure application services in multiple containers. Then, with a single command, you can create and start all the services from your configuration.
-
-## Prerequisites
-
-Make sure you have installed the following items on your machine:
-
-- [Git](https://git-scm.com/downloads)
-- [Docker Compose](https://docs.docker.com/compose/install/)
-- [MySQL Client](https://dev.mysql.com/downloads/mysql/)
-
-## Deploy TiDB using Docker Compose
-
-1. Download `tidb-docker-compose`.
-
- ```bash
- git clone https://github.com/pingcap/tidb-docker-compose.git
- ```
-
-2. Change the directory to tidb-docker-compose and get the latest TiDB Docker Images:
-
- ```bash
- cd tidb-docker-compose && docker-compose pull
- ```
-
-3. Start the TiDB cluster:
-
- ```bash
- docker-compose up -d
- ```
-
-4. Use the MySQL client to connect to TiDB to read and write data:
-
- ```
- mysql -h 127.0.0.1 -P 4000 -u root
- ```
-
-## Monitor the cluster
-
-After you have successfully deployed a TiDB cluster, you can now monitor the TiDB cluster using one of the following methods:
-
-- Use Grafana to view the status of the cluster via [http://localhost:3000](http://localhost:3000) with the default account name and password: `admin` and `admin`.
-- Use [TiDB-Vision](https://github.com/pingcap/tidb-vision), a cluster visualization tool, to see data transfer and load-balancing inside your cluster via [http://localhost:8010](http://localhost:8010).
-
-## Customize the cluster
-
-After the deployment is completed, the following components are deployed by default:
-
-- 3 PD instances, 3 TiKV instances, 1 TiDB instance
-- Monitoring components: Prometheus, Pushgateway, Grafana
-- Data visualization component: tidb-vision
-
-To customize the cluster, you can edit the `docker-compose.yml` file directly. It is recommended to generate `docker-compose.yml` using the [Helm](https://helm.sh) template engine, because manual editing is tedious and error-prone.
-
-1. Install Helm.
-
- [Helm](https://helm.sh) can be used as a template rendering engine. Make sure your Helm version >= 2.9.0 and < 3.0.0.
-
- To use Helm, you only need to download its binary file:
-
- ```bash
- curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get | bash
- ```
-
- For macOS, you can also install Helm using the following command in Homebrew:
-
- ```bash
- brew install helm@2
- brew link --force helm@2
- ```
-
-2. Download `tidb-docker-compose`.
-
- ```bash
- git clone https://github.com/pingcap/tidb-docker-compose.git
- ```
-
-3. Customize the cluster.
-
- ```bash
- cd tidb-docker-compose
- vim compose/values.yaml # custom the cluster size, docker image, port mapping and so on
- ```
-
- You can modify the configuration in `values.yaml`, such as the cluster size, TiDB image version, and so on.
-
- [tidb-vision](https://github.com/pingcap/tidb-vision) is the data visualization interface of the TiDB cluster, used to visually display the PD scheduling on TiKV data. If you do not need this component, comment out the `tidbVision` section.
-
- For PD, TiKV, TiDB and tidb-vision, you can build Docker images from GitHub source code or local files for development and testing.
-
- - To build PD, TiKV or TiDB images from the locally compiled binary file, you need to comment out the `image` field and copy the compiled binary file to the corresponding `pd/bin/pd-server`, `tikv/bin/tikv-server`, `tidb/bin/tidb-server`.
- - To build the tidb-vision image from local, you need to comment out the `image` field and copy the tidb-vision project to `tidb-vision/tidb-vision`.
-
-4. Generate the `docker-compose.yml` file.
-
- ```bash
- helm template compose > generated-docker-compose.yml
- ```
-
-5. Create and start the cluster using the generated `docker-compose.yml` file.
-
- ```bash
- docker-compose -f generated-docker-compose.yml pull # Get the latest Docker images
- docker-compose -f generated-docker-compose.yml up -d
- ```
-
-6. Access the cluster.
-
- ```bash
- mysql -h 127.0.0.1 -P 4000 -u root
- ```
-
- Access the Grafana monitoring interface:
-
- - Default address:
- - Default account name: admin
- - Default password: admin
-
- If tidb-vision is enabled, you can access the cluster data visualization interface: .
-
-## Access the Spark shell and load TiSpark
-
-Insert some sample data to the TiDB cluster:
-
-```bash
-$ docker-compose exec tispark-master bash
-$ cd /opt/spark/data/tispark-sample-data
-$ mysql -h tidb -P 4000 -u root < dss.ddl
-```
-
-After the sample data is loaded into the TiDB cluster, you can access the Spark shell using `docker-compose exec tispark-master /opt/spark/bin/spark-shell`.
-
-```bash
-$ docker-compose exec tispark-master /opt/spark/bin/spark-shell
-...
-Spark context available as 'sc' (master = local[*], app id = local-1527045927617).
-Spark session available as 'spark'.

-### How to deploy TiDB quickly using Docker Compose on a single machine?
-
-You can use Docker Compose to build a TiDB cluster locally, including the cluster monitoring components. You can also customize the version and number of instances for each component. The configuration file can also be customized. You can only use this deployment method for testing and development environment. For details, see [TiDB Docker Compose Deployment](/deploy-test-cluster-using-docker-compose.md).
-
### How to separately record the slow query log in TiDB? How to locate the slow query SQL statement?
1. The slow query definition for TiDB is in the TiDB configuration file. The `slow-threshold: 300` parameter is used to configure the threshold value of the slow query (unit: millisecond).

-# Deploy TiDB Using Docker
-
-> **Warning:**
->
-> The Docker deployment method provided in this document is no longer maintained. If you want to test TiDB, it is recommended to refer to [Quick Start Guide for the TiDB Database Platform](/quick-start-with-tidb.md) for deployment. For **production environment**, **do not use** Docker Compose for deployment, but [deploy TiDB with TiUP](/production-deployment-using-tiup.md) or [TiDB Operator in Kubernetes](https://docs.pingcap.com/tidb-in-kubernetes/stable/deploy-tidb-operator).
-
-This document shows you how to manually deploy a multi-node TiDB cluster on multiple machines using Docker.
-
-To learn more, see [TiDB architecture](/tidb-architecture.md) and [Software and Hardware Recommendations](/hardware-and-software-requirements.md).
-
-## Preparation
-
-Before you start, make sure that you have:
-
-+ Installed the latest version of [Docker](https://www.docker.com/products/docker)
-+ Pulled the latest images of TiDB, TiKV and PD from [Docker Hub](https://hub.docker.com/u/pingcap). If not, pull the images using the following commands:
-
- ```bash
- docker pull pingcap/tidb:latest
- docker pull pingcap/tikv:latest
- docker pull pingcap/pd:latest
- ```
-
-## Multi nodes deployment
-
-Assume we have 6 machines with the following details:
-

-$ mysql -h 127.0.0.1 -P 4000 -u root -D test
-mysql> show databases;
-+--------------------+
-| Database |
-+--------------------+
-| INFORMATION_SCHEMA |
-| PERFORMANCE_SCHEMA |
-| mysql |
-| test |
-+--------------------+
-4 rows in set (0.00 sec)
-```
-
-### How to customize the configuration file
-
-The TiKV and PD can be started with a specified configuration file, which includes some advanced parameters, for the performance tuning.
-
-Assume that the path to configuration file of PD and TiKV on the host is `/path/to/config/pd.toml` and `/path/to/config/tikv.toml`
-
-You can start TiKV and PD as follows:
-
-```bash
-docker run -d --name tikv1 \
- -p 20160:20160 \
- -v /etc/localtime:/etc/localtime:ro \
- -v /data:/data \
- -v /path/to/config/tikv.toml:/tikv.toml:ro \
- pingcap/tikv:latest \
- --addr="0.0.0.0:20160" \
- --advertise-addr="192.168.1.104:20160" \
- --data-dir="/data/tikv1" \
- --pd="192.168.1.101:2379,192.168.1.102:2379,192.168.1.103:2379" \
- --config="/tikv.toml"
-```
-
-```bash
-docker run -d --name pd1 \
- -p 2379:2379 \
- -p 2380:2380 \
- -v /etc/localtime:/etc/localtime:ro \
- -v /data:/data \
- -v /path/to/config/pd.toml:/pd.toml:ro \
- pingcap/pd:latest \

# Upgrade TiDB Using TiUP
-This document is targeted for users who want to upgrade from TiDB 4.0 versions to TiDB 5.0 versions, or from TiDB 5.0 to a later version.
+This document is targeted for the following upgrade paths:
-If your cluster to upgrade is v3.1 or an earlier version (v3.0 or v2.1), you need to upgrade your cluster first to v4.0 and then to v5.0. You cannot upgrade your cluster across a major version or versions.
+- Upgrade from TiDB 4.0 versions to TiDB 5.1 versions.
+- Upgrade from TiDB 5.0 versions to TiDB 5.1 versions.
+
+> **Note:**
+>
+> If your cluster to be upgraded is v3.1 or an earlier version (v3.0 or v2.1), the direct upgrade to v5.1 or its patch versions is not supported. You need to upgrade your cluster first to v4.0 and then to v5.1.
## Upgrade caveat
-- After the upgrade, rolling back to 4.0 or earlier versions is not supported.
-- For the v4.0 cluster managed using TiDB Ansible, you need to import the cluster to TiUP (`tiup cluster`) for new management according to [Upgrade TiDB Using TiUP (v4.0)](https://docs.pingcap.com/tidb/v4.0/upgrade-tidb-using-tiup#import-tidb-ansible-and-the-inventoryini-configuration-to-tiup). Then you can upgrade the cluster to v5.0 according to this document.

+# TiDB Sysbench Performance Test Report -- v5.1.0 vs. v5.0.2
+
+## Test overview
+
+This test aims at comparing the Sysbench performance of TiDB v5.1.0 and TiDB v5.0.2 in the Online Transactional Processing (OLTP) scenario. The results show that compared with v5.0.2, the Point Select performance of v5.1.0 is improved by 19.4%, and the performance of the Read Write and Update Index is slightly reduced.

+```
+
+## Test plan
+
+1. Deploy TiDB v5.1.0 and v5.0.2 using TiUP.
+2. Use Sysbench to import 16 tables, each table with 10 million rows of data.
+3. Execute the `analyze table` statement on each table.
+4. Back up the data used for restore before different concurrency tests, which ensures data consistency for each test.
+5. Start the Sysbench client to perform the `point_select`, `read_write`, `update_index`, and `update_non_index` tests. Perform stress tests on TiDB via HAProxy. The test takes 5 minutes.
+6. After each type of test is completed, stop the cluster, overwrite the cluster with the backup data in step 4, and restart the cluster.
+
+### Prepare test data
+
+Execute the following command to prepare the test data:
+
+{{< copyable "shell-regular" >}}
+
+```bash
+sysbench oltp_common \
+ --threads=16 \
+ --rand-type=uniform \
+ --db-driver=mysql \
+ --mysql-db=sbtest \
+ --mysql-host=$aws_nlb_host \
+ --mysql-port=$aws_nlb_port \
+ --mysql-user=root \
+ --mysql-password=password \
+ prepare --tables=16 --table-size=10000000
+```
+
+### Perform the test
+
+Execute the following command to perform the test:
+
+{{< copyable "shell-regular" >}}
+
+```bash
+sysbench $testname \
+ --threads=$threads \
+ --time=300 \
+ --report-interval=1 \
+ --rand-type=uniform \
+ --db-driver=mysql \
+ --mysql-db=sbtest \
+ --mysql-host=$aws_nlb_host \
