=== Update {dataframe-transform} API

Updates an existing {dataframe-transform}.

The API accepts a +{request}+ object as a request and returns a +{response}+.

[id="{upid}-{api}-request"]
==== Update {dataframe-transform} request

A +{request}+ requires the following argument:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------
<1> The update configuration with which to update the {dataframe-transform}.
<2> The ID of the configuration to update.
<3> Whether or not to wait to run deferrable validations until `_start` is called.
This option should be used with care as the created {dataframe-transform} will run
with the privileges of the user creating it. Meaning, if they do not have privileges,
such an error will not be visible until `_start` is called.

[id="{upid}-{api}-config"]
==== {dataframe-transform-cap} update configuration

The `DataFrameTransformConfigUpdate` object contains all the details about updated
{dataframe-transform} configuration and contains the following arguments:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-config]
--------------------------------------------------
<1> The source indices and query from which to gather data.
<2> The destination index and optional pipeline.
<3> How often to check for updates to the source indices.
<4> How to keep the {dataframe-transform} in sync with incoming data.
<5> Optional free text description of the transform.

[id="{upid}-{api}-response"]

The returned +{response}+ contains the updated {dataframe-transform} configuration 
or an error if the update failed or is invalid.
