Path parameters

• transform_id string | array[string] Required

  Identifier for the transform. It can be a transform identifier 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>.

Query parameters

• allow_no_match boolean

  Specifies what to do when the request:

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

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

• from number

  Skips the specified number of transforms.

• size number

  Specifies the maximum number of transforms to obtain.

• exclude_generated 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.

    • create_time_string string | number

      A date and time, either as a string whose format can depend on the context (defaulting to ISO 8601), or a number of milliseconds since the Epoch. Elasticsearch accepts both as input, but will generally output a string representation.

      • group_by object

        Defines how to group the data. More than one grouping can be defined per pivot. The following groupings are currently supported: date histogram, geotile grid, histogram, terms.

        • max_age string Required

          A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

    • settings object
      Hide settings attributes Show settings attributes object

      • align_checkpoints boolean

        Specifies whether the transform checkpoint ranges should be optimized for performance. Such optimization can align checkpoint ranges with the date histogram interval when date histogram is specified as a group source in the transform config. As a result, less document updates in the destination index will be performed thus improving overall performance.

      • dates_as_epoch_millis boolean

        Defines if dates in the ouput should be written as ISO formatted string or as millis since epoch. epoch_millis was the default for transforms created before version 7.11. For compatible output set this value to true.

      • deduce_mappings boolean

        Specifies whether the transform should deduce the destination index mappings from the transform configuration.

      • docs_per_second number

        Specifies a limit on the number of input documents per second. This setting throttles the transform by adding a wait time between search requests. The default value is null, which disables throttling.

      • max_page_search_size number

        Defines the initial page size to use for the composite aggregation for each checkpoint. If circuit breaker exceptions occur, the page size is dynamically adjusted to a lower value. The minimum value is 10 and the maximum is 65,536.

      • unattended boolean

        If true, the transform runs in unattended mode. In unattended mode, the transform retries indefinitely in case of an error which means the transform never fails. Setting the number of retries other than infinite fails in validation.
