        • enabled boolean

          If defined, it turns data stream lifecycle on/off (true/false) for this data stream. A data stream lifecycle that's disabled (enabled: false) will have no effect on the data stream.

        • rollover object
          Hide rollover attributes Show rollover attributes object
          • min_age string
