Get transforms API

edit

Get transforms API

edit

Retrieves configuration information for transforms.

Request

edit

GET _transform/<transform_id>

GET _transform/<transform_id>,<transform_id>

GET _transform/

GET _transform/_all

GET _transform/*

Prerequisites

edit

Requires the monitor_transform cluster privilege. This privilege is included in the transform_user built-in role.

Description

edit

You can get information for multiple transforms in a single API request by using a comma-separated list of identifiers or a wildcard expression. You can get information for all transforms by using _all, by specifying * as the <transform_id>, or by omitting the <transform_id>.

Path parameters

edit
<transform_id>
(Optional, string) Identifier for the transform. It can be a transform identifier or a wildcard expression. If you do not specify one of these options, the API returns information for all transforms.

Query parameters

edit
allow_no_match

(Optional, Boolean) Specifies what to do when the request:

  • Contains wildcard expressions and there are no transforms that match.
  • Contains the _all string or no identifiers and there are no matches.
  • Contains wildcard expressions and there are only partial matches.

The default value is true, which returns an empty transforms array when there are no matches and the subset of results when there are partial matches.

If this parameter is false, the request returns a 404 status code when there are no matches or only partial matches.

exclude_generated
(Optional, Boolean) Excludes fields that were automatically added when creating the transform. This allows the configuration to be in an acceptable format to be retrieved and then added to another cluster. Default is false.
from
(Optional, integer) Skips the specified number of transforms. The default value is 0.
size
(Optional, integer) Specifies the maximum number of transforms to obtain. The default value is 100.

Response body

edit

The API returns an array of transform resources, which are sorted by the id value in ascending order. For the full list of properties, see Create transform API.

create_time
(string) The time the transform was created. For example, 1576094542936. This property is informational; you cannot change its value.
version
(string) The transform configuration version number at which the trained model was created.

From Elasticsearch 8.10.0, a new version number is used to track the configuration and state changes in the transform plugin. This new version number is decoupled from the product version and will increment independently. The version value represents the new version number.

Response codes

edit
404 (Missing resources)
If allow_no_match is false, this code indicates that there are no resources that match the request or only partial matches for the request.

Examples

edit

The following example retrieves information about a maximum of ten transforms:

response = client.transform.get_transform(
  size: 10
)
puts response
GET _transform?size=10

The following example gets configuration information for the ecommerce_transform1 transform:

response = client.transform.get_transform(
  transform_id: 'ecommerce_transform1'
)
puts response
GET _transform/ecommerce_transform1

The API returns the following results:
