[[put-data-frame-transform-request]]
==== {api-request-title}

`PUT _data_frame/transforms/<data_frame_transform_id>`

[[put-data-frame-transform-prereqs]]
==== {api-prereq-title}

* If the {es} {security-features} are enabled, you must have
`manage_data_frame_transforms` cluster privileges to use this API. The built-in
`data_frame_transforms_admin` role has these privileges. You must also
have `read` and `view_index_metadata` privileges on the source index and `read`,
`create_index`, and `index` privileges on the destination index. For more
information, see {stack-ov}/security-privileges.html[Security privileges] and
{stack-ov}/built-in-roles.html[Built-in roles].

[[put-data-frame-transform-desc]]
==== {api-description-title}

IMPORTANT:  You must use {kib} or this API to create a {dataframe-transform}.
            Do not put a {dataframe-transform} directly into any
            `.data-frame-internal*` indices using the Elasticsearch index API.
            If {es} {security-features} are enabled, do not give users any
            privileges on `.data-frame-internal*` indices.

[[put-data-frame-transform-path-parms]]
==== {api-path-parms-title}

`<data_frame_transform_id>`::
  (Required, string) Identifier for the {dataframe-transform}. This identifier
  can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and
  underscores. It must start and end with alphanumeric characters.

[[put-data-frame-transform-query-parms]]
==== {api-query-parms-title}

`defer_validation`::
 (Optional, boolean) When `true`, deferrable validations are not run. This
 behavior may be desired if the source index does not exist until after the
{dataframe-transform} is created. Deferred validations are always run when the
{dataframe-transform} is started, with the exception of privilege checks. If the
user who created the transform does not have the required privileges on the
source and destination indices, the transform starts but then fails when it
attempts the unauthorized operation. The default value is `false`.

[[put-data-frame-transform-request-body]]
==== {api-request-body-title}

`description`::
  (Optional, string) Free text description of the {dataframe-transform}.

`dest`::
  (Required, object) Required. The destination configuration, which has the
  following properties:
  
  `index`:::
    (Required, string) The _destination index_ for the {dataframe-transform}.

  `pipeline`:::
    (Optional, string) The unique identifier for a <<pipeline,pipeline>>.

`frequency`::
  (Optional, time units) The interval between checks for changes in the source indices
  when the {dataframe-transform} is running continuously. Defaults to `1m`.
  The lowest permitted value is `1s`; the highest `1h`.

`pivot`::
  (Required, object) Defines the pivot function `group by` fields and the aggregation to
  reduce the data. See <<data-frame-transform-pivot>>.

`source`::
  (Required, object) The source configuration, which has the following
  properties:
  
  `index`:::
    (Required, string or array) The _source indices_ for the
    {dataframe-transform}. It can be a single index, an index pattern (for
    example, `"myindex*"`), or an array of indices (for example,
    `["index1", "index2"]`).
    
    `query`:::
      (Optional, object) A query clause that retrieves a subset of data from the
      source index. See <<query-dsl>>.
  
`sync`::
  (Optional, object) Defines the properties required to run continuously.
  `time`:::
    (Required, object) Specifies that the {dataframe-transform} uses a time
    field to synchronize the source and destination indices.
    `field`::::
      (Required, string) The date field that is used to identify new documents
      in the source.
+
--
TIP: In general, it’s a good idea to use a field that contains the
<<accessing-ingest-metadata,ingest timestamp>>. If you use a different field,
you might need to set the `delay` such that it accounts for data transmission
delays.

--
    `delay`::::
      (Optional, time units) The time delay between the current time and the
      latest input data time. The default value is `60s`.
