    • SUCCESS: The tuning succeeded.

    • FAILED: The tuning failed.

    • EXECUTING: The tuning is in progress.

    • TERMINATED: The tuning was terminated.

    • FAILED_WITH_ROLLBACK_SUCCESS: The tuning failed but the rollback succeeded.

    • FAILED_WITH_ROLLBACK_FAILED: The tuning failed and the rollback also failed.

    • FAILED_WITH_RESOURCE_LACK: The tuning failed due to insufficient resources.

    • FAILED_WITH_SAME_RESOURCE_SETTING: The tuning failed because the resource configuration did not change.

    SUCCESS
    tuningMessage

    string

    The tuning message. This is an internationalized, human-readable string that is not recommended for programmatic parsing.

    Scale up parallelism from 2 to 4
    triggerTime

    integer

    The trigger timestamp in milliseconds.
