=== Put {transform} API
|
|
|
|
Creates a new {transform}.
|
|
|
|
The API accepts a +{request}+ object as a request and returns a +{response}+.
|
|
|
|
[id="{upid}-{api}-request"]
|
|
==== Put {transform} 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 {transform} to create
|
|
<2> Whether or not to wait to run deferrable validations until `_start` is called.
|
|
This option should be used with care as the created {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"]
|
|
==== {transform-cap} configuration
|
|
|
|
The `TransformConfig` object contains all the details about the
|
|
{transform} configuration and contains the following arguments:
|
|

|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|

|
|
--------------------------------------------------
|
|
<1> The {transform} ID
|
|
<2> The source indices and query from which to gather data
|
|
<3> The destination index and optional pipeline
|
|
<4> How often to check for updates to the source indices
|
|
<5> The PivotConfig
|
|
<6> Optional free text description of the {transform}
|

[id="{upid}-{api}-query-config"]
|
|
|
|
==== SourceConfig
|
|
|
|
The indices and the query from which to collect data.
|
|
If query is not set, a `match_all` query is used by default.

|
through which the docs should be indexed

==== PivotConfig
|

include-tagged::{doc-tests-file}[{api}-pivot-config]
|
|
--------------------------------------------------
|
|
<1> The `GroupConfig` to use in the pivot
|
|
<2> The aggregations to use
|
|
<3> The maximum paging size for the {transform} when pulling data
|
|
from the source. The size dynamically adjusts as the {transform}
|
|
is running to recover from and prevent OOM issues.
|
|
|
|
===== GroupConfig
|
|
The grouping terms. Defines the group by and destination fields
|
|
which are produced by the pivot function. There are 3 types of
