Supervisor API
This topic describes the API endpoints to manage and monitor supervisors for Apache Druid.
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.
Supervisor information
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 Apache Kafka operations for details. |
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. |

Manage supervisors
Create or update a supervisor
Creates a new supervisor or updates an existing one for the same datasource with a new schema and configuration.
You can define a supervisor spec for Apache Kafka or Amazon Kinesis streaming ingestion methods. Once created, the supervisor persists in the metadata database.
When you call this endpoint on an existing supervisor for the same datasource, 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.
URL
POST /druid/indexer/v1/supervisor

Resume all supervisors
Resumes all supervisors. Note that this endpoint returns an HTTP 200 Success code even if there are no supervisors or suspended supervisors to resume.
URL
POST /druid/indexer/v1/supervisor/resumeAll
Responses
Successfully resumed all supervisors
Sample request
curl --request POST "http://ROUTER_IP:ROUTER_PORT/druid/indexer/v1/supervisor/resumeAll"

Reset a supervisor
Resets the specified supervisor. This endpoint clears stored offsets in Kafka or sequence numbers in Kinesis, prompting the supervisor to resume data reading. The supervisor will start from the earliest or latest available position, depending on the platform (offsets in Kafka or sequence numbers in Kinesis). It kills and recreates active tasks to read from valid positions.
Use this endpoint to recover from a stopped state due to missing offsets in Kafka or sequence numbers in Kinesis. Use this endpoint with caution as it may result in skipped messages and lead to data loss or duplicate data.
URL
POST /druid/indexer/v1/supervisor/:supervisorId/reset
Responses
Successfully reset supervisor
Invalid supervisor ID
Sample request
The following example shows how to reset a supervisor with the name social_media.
curl --request POST "http://ROUTER_IP:ROUTER_PORT/druid/indexer/v1/supervisor/social_media/reset"
POST /druid/indexer/v1/supervisor/social_media/reset HTTP/1.1

{
"id": "social_media"
}
Terminate a supervisor
Terminates a supervisor and its associated indexing tasks, triggering the publishing of their segments. When terminated, a tombstone marker is placed in the database to prevent reloading on restart.
The terminated supervisor still exists in the metadata store and its history can be retrieved.
URL
POST /druid/indexer/v1/supervisor/:supervisorId/terminate
Responses
Successfully terminated a supervisor
Invalid supervisor ID or supervisor not running
Sample request
curl --request POST "http://ROUTER_IP:ROUTER_PORT/druid/indexer/v1/supervisor/social_media/terminate"
