Class SequentialAckingBatchedTaskExecutor<Task extends AckedClusterStateUpdateTask>

java.lang.Object

org.elasticsearch.cluster.SimpleBatchedAckListenerTaskExecutor<Task>

org.elasticsearch.cluster.SequentialAckingBatchedTaskExecutor<Task>

Type Parameters:

Task - The type of the task that extends AckedClusterStateUpdateTask.

All Implemented Interfaces:

ClusterStateTaskExecutor<Task>

public class SequentialAckingBatchedTaskExecutor<Task extends AckedClusterStateUpdateTask>
extends SimpleBatchedAckListenerTaskExecutor<Task>

A task executor that executes tasks sequentially, allowing each task to acknowledge the cluster state update. This executor is used for tasks that need to be executed one after another, where each task can produce a new cluster state and can listen for acknowledgments.

Description copied from class: SimpleBatchedAckListenerTaskExecutor

Executes the provided task from the batch.

Specified by:

executeTask in class SimpleBatchedAckListenerTaskExecutor<Task extends AckedClusterStateUpdateTask>

Parameters:

task - The task to be executed.

clusterState - The cluster state on which the task should be executed.

Returns:

A tuple consisting of the resulting cluster state after executing this task, and a ClusterStateAckListener. The listener is completed if the publication succeeds and the nodes ack the state update. The returned cluster state serves as the cluster state on which the next task in the batch will run.

Throws:

Exception
