=== Get Rollup Job API
|
|
|
|
The Get Rollup Job API can be used to get one or all rollup jobs from the
|
|
cluster. It accepts a `GetRollupJobRequest` object as a request and returns
|
|
a `GetRollupJobResponse`.
|
|
|
|
[[java-rest-high-x-pack-rollup-get-rollup-job-request]]
|
|
==== Get Rollup Job Request
|
|
|
|
A `GetRollupJobRequest` can be built without any parameters to get all of the
|
|
rollup jobs or with a job name to get a single job:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/RollupDocumentationIT.java[x-pack-rollup-get-rollup-job-request]
|
|
--------------------------------------------------
|
|
<1> Gets all jobs.
|
|
<2> Gets `job_1`.
|
|
|
|
[[java-rest-high-x-pack-rollup-get-rollup-job-execution]]
|
|
==== Execution
|
|
|
|
The Get Rollup Job API can be executed through a `RollupClient`
|
|
instance. Such instance can be retrieved from a `RestHighLevelClient`
|
|
using the `rollup()` method:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/RollupDocumentationIT.java[x-pack-rollup-get-rollup-job-execute]
|
|
--------------------------------------------------
|
|
|
|
[[java-rest-high-x-pack-rollup-get-rollup-job-response]]
|
|
==== Response
|
|
|
|
The returned `GetRollupJobResponse` includes a `JobWrapper` per returned job
|
|
which contains the configuration of the job, the job's current status, and
|
|
statistics about the job's past execution.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/RollupDocumentationIT.java[x-pack-rollup-get-rollup-job-response]
|
|
--------------------------------------------------
|
|
<1> We only asked for a single job
|
|
|
|
[[java-rest-high-x-pack-rollup-get-rollup-job-async]]
|
|
==== Asynchronous Execution
|
|
|
|
This request can be executed asynchronously:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/RollupDocumentationIT.java[x-pack-rollup-get-rollup-job-execute-async]
|
|
--------------------------------------------------
|
|
<1> The `GetRollupJobRequest` 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.
|
|
|
|
A typical listener for `GetRollupJobResponse` looks like:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/RollupDocumentationIT.java[x-pack-rollup-get-rollup-job-execute-listener]
|
|
--------------------------------------------------
|
|
<1> Called when the execution is successfully completed. The response is
|
|
provided as an argument
|
|
<2> Called in case of failure. The raised exception is provided as an argument
|
