=== Put datafeed API
Creates a new {ml} datafeed in the cluster. The API accepts a +{request}+ object
as a request and returns a +{response}+.
[id="{upid}-{api}-request"]
==== Put datafeed request
A +{request}+ requires the following argument:
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------
<1> The configuration of the {ml} datafeed to create.
[id="{upid}-{api}-config"]
==== Datafeed configuration
The `DatafeedConfig` object contains all the details about the {ml} datafeed
configuration.
A `DatafeedConfig` requires the following arguments:
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-config]
--------------------------------------------------
<1> The datafeed ID and the {anomaly-job} ID.
<2> The indices that contain the data to retrieve and feed into the {anomaly-job}.
==== Optional arguments
The following arguments are optional:
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-config-set-chunking-config]
--------------------------------------------------
<1> Specifies how data searches are split into time chunks.
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-config-set-frequency]
--------------------------------------------------
<1> The interval at which scheduled queries are made while the datafeed runs in
real time.
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-config-set-query]
--------------------------------------------------
<1> A query to filter the search results by. Defaults to the `match_all` query.
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-config-set-query-delay]
--------------------------------------------------
<1> The time interval behind real time that data is queried.
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-config-set-delayed-data-check-config]
--------------------------------------------------
<1> Sets the delayed data check configuration.
The window must be larger than the Job's bucket size, but smaller than 24 hours,
and span less than 10,000 buckets.
Defaults to `null`, which causes an appropriate window span to be calculated when
the datafeed runs.
The default `check_window` span calculation is the max between `2h` or
`8 * bucket_span`. To explicitly disable, pass
`DelayedDataCheckConfig.disabledDelayedDataCheckConfig()`.
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-config-set-script-fields]
--------------------------------------------------
<1> Allows the use of script fields.
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-config-set-scroll-size]
--------------------------------------------------
<1> The `size` parameter used in the searches.

[id="{upid}-{api}-response"]
==== Response
The returned +{response}+ returns the full representation of
the new {ml} datafeed if it has been successfully created. This will
contain the creation time and other fields initialized using
default values:
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-response]
--------------------------------------------------
<1> The created datafeed.
