Creating an Event

This section describes how to create an event to periodically respond to specific operations.

If you set event_scheduler to ON and enable the event function, you can manage events.

When event_scheduler is set to OFF, but the event function is enabled, you can only create events and the events do not take effect.

  2. Click in the upper left corner and select a region and project.
  3. Click in the upper left corner, and under Databases, click Data Admin Service.
  4. In the navigation pane on the left, choose Development Tool.

  6. On the top menu bar, choose Database Management.
