API reference

This page documents all of the API endpoints for each Druid service type.

Common

The following endpoints are supported by all processes.

Process information

GET

  • /status

Returns the Druid version, loaded extensions, memory used, total memory and other useful information about the process.

  • /status/health

An endpoint that always returns a boolean “true” value with a 200 OK response, useful for automated health checks.

  • /status/properties

Returns the current configuration properties of the process.

  • /status/selfDiscovered/status

Returns a JSON map of the form {"selfDiscovered": true/false}, indicating whether the node has received a confirmation from the central node discovery mechanism (currently ZooKeeper) of the Druid cluster that the node has been added to the cluster. It is recommended to not consider a Druid node “healthy” or “ready” in automated deployment/container management systems until it returns {"selfDiscovered": true} from this endpoint. This is because a node may be isolated from the rest of the cluster due to network issues and it doesn’t make sense to consider nodes “healthy” in this case. Also, when nodes such as Brokers use ZooKeeper segment discovery for building their view of the Druid cluster (as opposed to HTTP segment discovery), they may be unusable until the ZooKeeper client is fully initialized and starts to receive data from the ZooKeeper cluster. {"selfDiscovered": true} is a proxy event indicating that the ZooKeeper client on the node has started to receive data from the ZooKeeper cluster and it’s expected that all segments and other nodes will be discovered by this node timely from this point.

  • /status/selfDiscovered

Similar to /status/selfDiscovered/status, but returns 200 OK response with empty body if the node has discovered itself and 503 SERVICE UNAVAILABLE if the node hasn’t discovered itself yet. This endpoint might be useful because some monitoring checks such as AWS load balancer health checks are not able to look at the response body.

Master Server

This section documents the API endpoints for the processes that reside on Master servers (Coordinators and Overlords) in the suggested three-server configuration.

Coordinator

Leadership

GET
  • /druid/coordinator/v1/leader

Returns the current leader Coordinator of the cluster.

  • /druid/coordinator/v1/isLeader

Returns a JSON object with field “leader”, either true or false, indicating if this server is the current leader Coordinator of the cluster. In addition, returns HTTP 200 if the server is the current leader and HTTP 404 if not. This is suitable for use as a load balancer status check if you only want the active leader to be considered in-service at the load balancer.

Segment Loading

GET
  • /druid/coordinator/v1/loadstatus

Returns the percentage of segments actually loaded in the cluster versus segments that should be loaded in the cluster.

  • /druid/coordinator/v1/loadstatus?simple

Returns the number of segments left to load until segments that should be loaded in the cluster are available for queries. This does not include replication.

  • /druid/coordinator/v1/loadstatus?full

Returns the number of segments left to load in each tier until segments that should be loaded in the cluster are all available. This includes replication.

  • /druid/coordinator/v1/loadqueue

Returns the ids of segments to load and drop for each Historical process.

  • /druid/coordinator/v1/loadqueue?simple

Returns the number of segments to load and drop, as well as the total segment load and drop size in bytes for each Historical process.

Note that all interval URL parameters are ISO 8601 strings delimited by a _ instead of a / (e.g., 2016-06-27_2016-06-28).

Note for coordinator’s POST and DELETE API’s

The segments would be enabled when these API’s are called, but then can be disabled again by the coordinator if any dropRule matches. Segments enabled by these API’s might not be loaded by historical processes if no loadRule matches. If an indexing or kill task runs at the same time as these API’s are invoked, the behavior is undefined. Some segments might be killed and others might be enabled. It’s also possible that all segments might be disabled but at the same time, the indexing task is able to read data from those segments and succeed.

Caution : Avoid using indexing or kill tasks and these API’s at the same time for the same datasource and time chunk. (It’s fine if the time chunks or datasource don’t overlap)

POST
  • /druid/coordinator/v1/datasources/{dataSourceName}

Marks as used all segments belonging to a data source. Returns a JSON object of the form {"numChangedSegments": <number>} with the number of segments in the database whose state has been changed (that is, the segments were marked as used) as the result of this API call.

  • /druid/coordinator/v1/datasources/{dataSourceName}/segments/{segmentId}

Marks as used a segment of a data source. Returns a JSON object of the form {"segmentStateChanged": <boolean>} with the boolean indicating if the state of the segment has been changed (that is, the segment was marked as used) as the result of this API call.

  • /druid/coordinator/v1/datasources/{dataSourceName}/markUsed

  • /druid/coordinator/v1/datasources/{dataSourceName}/markUnused

Marks segments (un)used for a datasource by interval or set of segment Ids.

When marking used only segments that are not overshadowed will be updated.

The request payload contains the interval or set of segment Ids to be marked unused. Either interval or segment ids should be provided, if both or none are provided in the payload, the API would throw an error (400 BAD REQUEST).

Interval specifies the start and end times as IS0 8601 strings. interval=(start/end) where start and end both are inclusive and only the segments completely contained within the specified interval will be disabled, partially overlapping segments will not be affected.

JSON Request Payload:

KeyDescriptionExample
intervalThe interval for which to mark segments unused“2015-09-12T03:00:00.000Z/2015-09-12T05:00:00.000Z”
segmentIdsSet of segment Ids to be marked unused[“segmentId1”, “segmentId2”]
