1
PlannedStartTimestringNo

The earliest start time of the scheduled task for adding the read-only node. The scheduled task specifies that the task is run in the required period. Specify the time in the YYYY-MM-DDThh:mm:ssZ format. The time must be in UTC.

Note
  • The earliest start time of the scheduled task can be a point in time within the next 24 hours. For example, if the current time is 2021-01-14T09:00:00Z, you can specify a point in time between 2021-01-14T09:00:00Z and 2021-01-15T09:00:00Z.
  • If you leave this parameter empty, the task for adding the read-only node is immediately run by default.
  • 2021-01-14T09:00:00Z
    PlannedEndTimestringNo

    The latest start time for upgrading the specifications within the scheduled time period. Specify the time in the YYYY-MM-DDThh:mm:ssZ format. The time must be in UTC.

    Note
  • The value of this parameter must be at least 30 minutes later than the value of PlannedStartTime.
  • If you specify PlannedStartTime but do not specify PlannedEndTime, the latest start time of the task is set to a value that is calculated by using the following formula: PlannedEndTime value + 30 minutes. For example, if you set PlannedStartTime to 2021-01-14T09:00:00Z and you do not specify PlannedEndTime, the latest start time of the task is set to 2021-01-14T09:30:00Z.
  • 2021-01-14T09:30:00Z
    FromTimeServicebooleanNo

    Specifies an immediate or scheduled task to modify parameters and restart the cluster. Valid values:

    • false: scheduled task
    • true: immediate task
    false
