=== Get Records API

The Get Records API retrieves one or more record results.
It accepts a `GetRecordsRequest` object and responds
with a `GetRecordsResponse` object.

[[java-rest-high-x-pack-ml-get-records-request]]
==== Get Records Request

A `GetRecordsRequest` object gets created with an existing non-null `jobId`.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-request]
--------------------------------------------------
<1> Constructing a new request referencing an existing `jobId`

==== Optional Arguments
The following arguments are optional:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-desc]
--------------------------------------------------
<1> If `true`, the records are sorted in descending order. Defaults to `false`.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-end]
--------------------------------------------------
<1> Records with timestamps earlier than this time will be returned.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-exclude-interim]
--------------------------------------------------
<1> If `true`, interim results will be excluded. Defaults to `false`.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-page]
--------------------------------------------------
<1> The page parameters `from` and `size`. `from` specifies the number of records to skip.
`size` specifies the maximum number of records to get. Defaults to `0` and `100` respectively.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-record-score]
--------------------------------------------------
<1> Records with record_score greater or equal than this value will be returned.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-sort]
--------------------------------------------------
<1> The field to sort records on. Defaults to `influencer_score`.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-end]
--------------------------------------------------
<1> Records with timestamps on or after this time will be returned.

[[java-rest-high-x-pack-ml-get-records-execution]]
==== Execution

The request can be executed through the `MachineLearningClient` contained
in the `RestHighLevelClient` object, accessed via the `machineLearningClient()` method.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-execute]
--------------------------------------------------


[[java-rest-high-x-pack-ml-get-records-execution-async]]
==== Asynchronous Execution

The request can also be executed asynchronously:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-execute-async]
--------------------------------------------------
<1> The `GetRecordsRequest` 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 with the `onResponse` method
if the execution is successful or the `onFailure` method if the execution
failed.

A typical listener for `GetRecordsResponse` looks like:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-listener]
--------------------------------------------------
<1> `onResponse` is called back when the action is completed successfully
<2> `onFailure` is called back when some unexpected error occurs

[[java-rest-high-snapshot-ml-get-records-response]]
==== Get Records Response

The returned `GetRecordsResponse` contains the requested records:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-records-response]
--------------------------------------------------
<1> The count of records that were matched
<2> The records retrieved
