This topic describes the API endpoints to manage and monitor supervisors for Apache Druid. The topic uses the Apache Kafka term offset to refer to the identifier for records in a partition. If you are using Amazon Kinesis, the equivalent is sequence number.
In this topic, http://ROUTER_IP:ROUTER_PORT is a placeholder for your Router service address and port. Replace it with the information for your deployment. For example, use http://localhost:8888 for quickstart deployments.
The following table lists the properties of a supervisor object:
| Property | Type | Description |
|---|---|---|
id |
String | Unique identifier. |
state |
String | Generic state of the supervisor. Available states:UNHEALTHY_SUPERVISOR, UNHEALTHY_TASKS, PENDING, RUNNING, SUSPENDED, STOPPING. See Supervisor reference for more information. |
detailedState |
String | Detailed state of the supervisor. This property contains a more descriptive, implementation-specific state that may provide more insight into the supervisor's activities than the state property. See Apache Kafka ingestion and Amazon Kinesis ingestion for supervisor-specific states. |
healthy |
Boolean | Supervisor health indicator. |
spec |
Object | Container object for the supervisor configuration. |
suspended |
Boolean | Indicates whether the supervisor is in a suspended state. |
Returns an array of strings representing the names of active supervisors. If there are no active supervisors, it returns an empty array.

}Retrieves the current health report for a single supervisor. The health of a supervisor is determined by the supervisor's state (as returned by the /status endpoint) and the druid.supervisor.* Overlord configuration thresholds.
GET /druid/indexer/v1/supervisor/{supervisorId}/health
Supervisor is healthy
Invalid supervisor ID
Supervisor is unhealthy
The following example shows how to retrieve the health report for a supervisor with the name social_media.

}Returns a snapshot of the current ingestion row counters for each task being managed by the supervisor, along with moving averages for the row counters. See Row stats for more information.
The response is a nested map of task group IDs to task IDs to row stats:
{
"<taskGroupId>": {
"<taskId>": {
"movingAverages": { ... },
"totals": { ... }
}
}
}- taskGroupId (string): Supervisor task group identifier
- taskId (string): Druid indexing task identifier within that group
- movingAverages / totals: Per-task row stats; see Row stats for field definitions
For example, a supervisor with two task groups:
{
"0": {
"index_kafka_my_datasource_abc123": {
"movingAverages": {
"buildSegments": {
"5m": { "processed": 10.0, "unparseable": 0.0, "thrownAway": 0.0, "processedWithError": 0.0 },
"15m": { "processed": 5.0, "unparseable": 0.0, "thrownAway": 0.0, "processedWithError": 0.0 },
"1m": { "processed": 12.0, "unparseable": 0.0, "thrownAway": 0.0, "processedWithError": 0.0 }
}
},
"totals": {
"buildSegments": { "processed": 2000, "processedWithError": 0, "thrownAway": 0, "unparseable": 0 }
}
}
},

"movingAverages": {

}
},
"totals": {

}
}
}
}In this example, "0" and "1" are task group IDs, and index_kafka_my_datasource_abc123 and index_kafka_my_datasource_def456 are task IDs.

}For automation clients: If you need to map task IDs to group IDs (for handoff, draining, or observability), use the /stats response keys directly instead of re-deriving group IDs from partition data. This avoids coupling to internal supervisor assignment logic.

]Creates a new supervisor spec or updates an existing one with new configuration and schema information. When updating a supervisor spec, the datasource must remain the same as the previous supervisor.
You can define a supervisor spec for Apache Kafka or Amazon Kinesis streaming ingestion methods.
The following table lists the properties of a supervisor spec:
| Property | Type | Description | Required |
|---|---|---|---|
type |
String | The supervisor type. One ofkafka or kinesis. |
Yes |
spec |
Object | The container object for the supervisor configuration. | Yes |
ioConfig |
Object | The I/O configuration object to define the connection and I/O-related settings for the supervisor and indexing task. | Yes |
dataSchema |
Object | The schema for the indexing task to use during ingestion. See dataSchema for more information. |
Yes |
tuningConfig |
Object | The tuning configuration object to define performance-related settings for the supervisor and indexing tasks. | No |
When you call this endpoint on an existing supervisor, the running supervisor signals its tasks to stop reading and begin publishing, exiting itself. Druid then uses the provided configuration from the request body to create a new supervisor. Druid submits a new schema while retaining existing publishing tasks and starts new tasks at the previous task offsets. This way, you can apply configuration changes without a pause in ingestion.

}The supervisor must be running for this endpoint to be available.
Resets the specified supervisor. This endpoint clears supervisor metadata, prompting the supervisor to resume data reading. The supervisor restarts from the earliest or latest available position, depending on the value of the useEarliestOffset property.
After clearing all stored offsets, the supervisor kills and recreates active tasks,
so that tasks begin reading from valid positions.
Use this endpoint to recover from a stopped state due to missing offsets. Use this endpoint with caution as it may result in skipped messages and lead to data loss or duplicate data.
The indexing service keeps track of the latest persisted offsets to provide exactly-once ingestion guarantees across tasks. Subsequent tasks must start reading from where the previous task completed for Druid to accept the generated segments. If the messages at the expected starting offsets are no longer available, the supervisor refuses to start and in-flight tasks fail. Possible causes for missing messages include the message retention period elapsing or the topic being removed and re-created. Use the reset endpoint to recover from this condition.

Resets the specified offsets for partitions without resetting the entire set.
This endpoint clears only the stored offsets, prompting the supervisor to resume reading data from the specified offsets. If there are no stored offsets, the specified offsets are set in the metadata store.
After resetting stored offsets, the supervisor kills and recreates any active tasks pertaining to the specified partitions, so that tasks begin reading specified offsets. For partitions that are not specified in this operation, the supervisor resumes from the last stored offset.
Use this endpoint with caution. It can cause skipped messages, leading to data loss or duplicate data.
POST /druid/indexer/v1/supervisor/{supervisorId}/resetOffsets
Successfully reset offsets
Invalid supervisor ID
This section presents the structure and details of the reset offsets metadata payload.
| Field | Type | Description | Required |
|---|---|---|---|
type |
String | The type of reset offsets metadata payload. It must match the supervisor's type. Possible values: kafka or kinesis. |
Yes |
partitions |
Object | An object representing the reset metadata. See below for details. | Yes |
The following table defines the fields within the partitions object in the reset offsets metadata payload.
| Field | Type | Description | Required |
|---|---|---|---|
type |
String | Must be set as end. Indicates the end sequence numbers for the reset offsets. |
Yes |
stream |
String | The stream to be reset. It must be a valid stream consumed by the supervisor. | Yes |
partitionOffsetMap |
Object | A map of partitions to corresponding offsets for the stream to be reset. | Yes |
The following example shows how to reset offsets for a Kafka supervisor with the name social_media. For example, the supervisor is reading from a Kafka topic ads_media_stream and has the stored offsets: {"0": 0, "1": 10, "2": 20, "3": 40}.
curl --request POST "http://ROUTER_IP:ROUTER_PORT/druid/indexer/v1/supervisor/social_media/resetOffsets"

"partitions": {

}
}The example operation resets offsets only for partitions 0 and 2 to 100 and 650 respectively. After a successful reset,
when the supervisor's tasks restart, they resume reading from {"0": 100, "1": 10, "2": 650, "3": 40}.
