Get transforms Generally available

GET /_transform
Api key auth

Get configuration information for transforms.

Required authorization

  • Cluster privileges: monitor_transform

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.

        • unique_key array[string] Required

          Specifies an array of one or more fields that are used to group the data.

      • pivot object
        Hide pivot attributes Show pivot attributes object

The following aggregations are currently supported: average, bucket script, bucket selector, cardinality, filter, geo bounds, geo centroid, geo line, max, median absolute deviation, min, missing, percentiles, rare terms, scripted metric, stats, sum, terms, top metrics, value count, weighted average.

        • group_by object

          • 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

        The source of the data for the transform.

        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 Generally available

          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.
