Task Scheduler

Overview

The Task Scheduler component is used to schedule data between data sources. It is mainly used to set the integration mode and execution period of tasks.

Configuration

  • Using the QuartZ Cron expression

    The QuartZ Cron expression supports flexible schedules. For example, a task can be executed every 15 minutes from 01:00 a.m. to 04:00 a.m. every day. Such schedules cannot be implemented through simple GUI configuration, but by QuartZ Cron expression.

    0 0/15 1-4 * * ?

    Parameter

    Description

    Use QuartZ Cron Expression

    Select Yes.

    QuartZ Cron Expression

    Specify the QuartZ Cron expression for the schedule. Currently, ROMA Connect supports only minute-level schedules. Second in the expression is fixed to 0. For details about how to use the QuartZ Cron expression, see How Can I Configure the Time for Triggering a Scheduled Task?

    For example, if a task needs to be executed every 15 minutes from 01:00 a.m. to 04:00 a.m. every day, the QuartZ Cron expression corresponding to the schedule is as follows:

    0 0/15 1-4 * * ?

    Execution Time

    Specify the time at which you want the task to be executed. The task will be executed in the subsequent scheduling period.

    For example, if Execution Time is set to 2020-2-2 02:02:02 and QuartZ Cron Expression is set as above, the task is executed for the first time at 2020-2-3 02:15:00.

    Parameter

    Description

    Use QuartZ Cron Expression

    Select No.

    Unit

    Set the unit of the task execution period. The value can be Minute, Hour, Day, Week, or Month.

    Period

    Set the task execution cycle. The value range varies depending on the value of Unit.

    For example, if Unit is set to Day and Period is set to 1, the data integration task is executed once every day.

    Execution Time

    Specify the time at which you want the task to be executed. The task will be executed in the subsequent scheduling period.

    For example, if Execution Time is set to 2020-2-2 02:02:02 and the scheduling period is one day, the task is executed for the first time at 2020-2-3 02:02:02.

    Description
