=== Post Data API
|
|
|
|
The Post Data API provides the ability to post data to an open
|
|
{ml} job in the cluster.
|
|
It accepts a `PostDataRequest` object and responds
|
|
with a `PostDataResponse` object.
|
|
|
|
[[java-rest-high-x-pack-ml-post-data-request]]
|
|
==== Post Data Request
|
|
|
|
A `PostDataRequest` object gets created with an existing non-null `jobId`
|
|
and the `XContentType` being sent. Individual docs can be added
|
|
incrementally via the `PostDataRequest.JsonBuilder#addDoc` method.
|
|
These are then serialized and sent in bulk when passed to the `PostDataRequest`.
|
|
|
|
Alternatively, the serialized bulk content can be set manually, along with its `XContentType`
|
|
through one of the other `PostDataRequest` constructors.
|
|
|
|
Only `XContentType.JSON` and `XContentType.SMILE` are supported.

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

|
==== Asynchronous Execution
|
|
|
|
The request can also be executed asynchronously:

|
|
<1> The `PostDataRequest` to execute and the `ActionListener` to use when
|
|
the execution completes
|
|
|
|
The method does not block and returns immediately. The passed `ActionListener` is used
|
|
to notify the caller of completion. A typical `ActionListener` for `PostDataResponse` may
|
|
look like

|
==== Post Data Response
|
|
|
|
A `PostDataResponse` contains current data processing statistics.
