This document describes the API endpoints for task retrieval, submission, and deletion for Apache Druid. Tasks are individual jobs performed by Druid to complete operations such as ingestion, querying, and compaction.

In this topic, `http://ROUTER_IP:ROUTER_PORT` is a placeholder for the Router service address and port. For example, on the quickstart configuration, use `http://localhost:8888`.

## Task information and retrieval

### Get an array of tasks

Retrieves an array of all tasks in the Druid cluster. Each task object includes information on its ID, status, associated datasource, and other metadata. For definitions of the response properties, see the [Tasks table](../querying/sql-metadata-tables.md#tasks-table).

#### URL

<code class="getAPI">GET</code> <code>/druid/indexer/v1/tasks</code>

#### Query parameters

The endpoint supports a set of optional query parameters to filter results.

|Parameter|Type|Description|
|---|---|---|
|`state`|String|Filter list of tasks by task state, valid options are `running`, `complete`, `waiting`, and `pending`.|
| `datasource`|String| Return tasks filtered by Druid datasource.|
| `createdTimeInterval`|String (ISO-8601)| Return tasks created within the specified interval. Use `_` as the delimiter for the interval string. Do not use `/`. For example, `2023-06-27_2023-06-28`.|
| `max`|Integer|Maximum number of `complete` tasks to return. Only applies when `state` is set to `complete`.|
| `type`|String|Filter tasks by task type. See [task documentation](../ingestion/tasks.md) for more details.|

### Get task segments

:::info
 This API is deprecated and will be removed in future releases.
:::

Retrieves information about segments generated by the task given the task ID. To hit this endpoint, make sure to enable the audit log config on the Overlord with `druid.indexer.auditLog.enabled = true`.

In addition to enabling audit logs, configure a cleanup strategy to prevent overloading the metadata store with old audit logs which may cause performance issues. To enable automated cleanup of audit logs on the Coordinator, set `druid.coordinator.kill.audit.on`. You may also manually export the audit logs to external storage. For more information, see [Audit records](../operations/clean-metadata-store.md#audit-records).

#### Sample response

A successful request returns a `200 OK` response and an array of the task segments.

### Get task log

Retrieves the event log associated with a task. It returns a list of logged events during the lifecycle of the task. The endpoint is useful for providing information about the execution of the task, including any errors or warnings raised.

Task logs are automatically retrieved from the Middle Manager/Indexer or in long-term storage. For reference, see [Task logs](../ingestion/tasks.md#task-logs).

## Task operations

### Submit a task

Submits a JSON-based ingestion spec or supervisor spec to the Overlord. It returns the task ID of the submitted task. For information on creating an ingestion spec, refer to the [ingestion spec reference](../ingestion/ingestion-spec.md).

Note that for most batch ingestion use cases, you should use the [SQL-ingestion API](./sql-ingestion-api.md) instead of JSON-based batch ingestion.
