Start Rollup Job APIedit

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.


The Start Rollup Job API allows you to start a job by ID.

StartRollupJobRequest request = new StartRollupJobRequest(id); 

The ID of the job to start.


The returned StartRollupJobResponse indicates if the start command was received.


Whether or not the start job request was received.

Synchronous executionedit

When executing a StartRollupJobRequest in the following manner, the client waits for the StartRollupJobResponse to be returned before continuing with code execution:

RollupClient rc = client.rollup();
StartRollupJobResponse response = rc.startRollupJob(request, RequestOptions.DEFAULT);

Synchronous calls may throw an IOException in case of either failing to parse the REST response in the high-level REST client, the request times out or similar cases where there is no response coming back from the server.

In cases where the server returns a 4xx or 5xx error code, the high-level client tries to parse the response body error details instead and then throws a generic ElasticsearchException and adds the original ResponseException as a suppressed exception to it.

Asynchronous executionedit

Executing a StartRollupJobRequest can also be done in an asynchronous fashion so that the client can return directly. Users need to specify how the response or potential failures will be handled by passing the request and a listener to the asynchronous rollup-start-job method:

RollupClient rc = client.rollup();
rc.startRollupJobAsync(request, RequestOptions.DEFAULT, listener); 

The StartRollupJobRequest to execute and the ActionListener to use when the execution completes

The asynchronous method does not block and returns immediately. Once it is completed the ActionListener is called back using the onResponse method if the execution successfully completed or using the onFailure method if it failed. Failure scenarios and expected exceptions are the same as in the synchronous execution case.

A typical listener for rollup-start-job looks like:

ActionListener<StartRollupJobResponse> listener = new ActionListener<StartRollupJobResponse>() {
    public void onResponse(StartRollupJobResponse response) {
    public void onFailure(Exception e) {

Called when the execution is successfully completed.

Called when the whole StartRollupJobRequest fails.
