Description

This is a DolphinScheduler project of OSPP-2023
This implementation allows to add listeners for monitoring and tracking the workflow/task state using plugins without restarting the service.

  1. Users can customize listener plugins by building a plugin JAR which implemented the methods in ListenerPlugin and registering it in Security module.
  2. Users can create listener instances with the listener plugin and choose the listener events to subscribe to in Security module.
  3. The listener events monitored by the listener instance will be pushed to the specified destination (message queues, external system interfaces, etc.).
