## Supervisor information
2023-06-26 18:48:54 -04:00
2023-07-27 15:58:37 -04:00
The following table lists the properties of a supervisor object:
2023-06-26 18:48:54 -04:00
2023-07-27 15:58:37 -04:00
|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 ](../development/extensions-core/kafka-supervisor-operations.md ) 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 ](../development/extensions-core/kafka-ingestion.md ) and [Amazon Kinesis ingestion ](../development/extensions-core/kinesis-ingestion.md ) 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
2023-08-16 22:01:21 -04:00
Creates a new supervisor or updates an existing one for the same datasource with a new schema and configuration.
2023-07-27 15:58:37 -04:00
You can define a supervisor spec for [Apache Kafka ](../development/extensions-core/kafka-ingestion.md#define-a-supervisor-spec ) or [Amazon Kinesis ](../development/extensions-core/kinesis-ingestion.md#supervisor-spec ) 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.

### Reset a supervisor
2023-08-17 17:13:10 -04:00
Resets the specified supervisor. This endpoint clears _all_ 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.
2023-07-27 15:58:37 -04:00
2023-08-16 22:01:21 -04:00
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.

### Reset Offsets for a supervisor
Resets the specified offsets for a supervisor. This endpoint clears _only_ the specified offsets in Kafka or sequence numbers in Kinesis, prompting the supervisor to resume data reading.
If there are no stored offsets, the specified offsets will be set in the metadata store. The supervisor will start from the reset offsets for the partitions specified and for the other partitions from the stored offset.
It kills and recreates active tasks pertaining to the partitions specified to read from valid offsets.
Use this endpoint to selectively reset offsets for partitions without resetting the entire set.

#### Reset Offsets Metadata
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 |
#### Partitions
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 |
#### Sample request
The following example shows how to reset offsets for a kafka supervisor with the name `social_media` . Let's say the supervisor is reading
from a kafka topic `ads_media_stream` and has the stored offsets: `{"0": 0, "1": 10, "2": 20, "3": 40}` .
<!-- DOCUSAURUS_CODE_TABS -->
<!-- cURL -->
```shell
curl --request POST "http://ROUTER_IP:ROUTER_PORT/druid/indexer/v1/supervisor/social_media/resetOffsets"
--header 'Content-Type: application/json'
--data-raw '{"type":"kafka","partitions":{"type":"end","stream":"ads_media_stream","partitionOffsetMap":{"0":100, "2": 650}}}'
```
<!-- HTTP -->
```HTTP
POST /druid/indexer/v1/supervisor/social_media/resetOffsets HTTP/1.1
Host: http://ROUTER_IP:ROUTER_PORT
Content-Type: application/json
{
"type": "kafka",
"partitions": {
"type": "end",
"stream": "ads_media_stream",
"partitionOffsetMap": {
"0": 100,
"2": 650
}
}
}
```
The above operation will reset offsets only for partitions 0 and 2 to 100 and 650 respectively. After a successful reset,
when the supervisor's tasks restart, they will resume reading from `{"0": 100, "1": 10, "2": 650, "3": 40}` .

### Terminate a supervisor
2023-08-16 22:01:21 -04:00
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.
2023-07-27 15:58:37 -04:00
The terminated supervisor still exists in the metadata store and its history can be retrieved.
