[CalvinKirs]

effect version 2.0

• How to reproduce：

CREATE TABLE `user` (
  `id` bigint(20) NOT NULL COMMENT '用户ID',
  `user_name` text NULL,
  `password` text NULL,
   ...
) ENGINE=OLAP
UNIQUE KEY(`id`)
COMMENT 'OLAP'
PARTITION BY RANGE(`id`)
(PARTITION i1 VALUES [("-9223372036854775808"), ("5000000")),
PARTITION i2 VALUES [("5000000"), ("10000000")),
DISTRIBUTED BY HASH(`id`) BUCKETS 16
PROPERTIES (
"replication_allocation" = "tag.location.default: 1",
"is_being_synced" = "false",
"storage_format" = "V2",
"enable_unique_key_merge_on_write" = "true",
"light_schema_change" = "true",
"function_column.sequence_col" = "order_id",
"disable_auto_compaction" = "false",
"enable_single_replica_compaction" = "false"
);

CREATE ROUTINE LOAD test_load ON user

COLUMNS TERMINATED BY ",",
