In Camunda, a timer event is a type of event that can automatically trigger a task or action within a specific time or interval. The use of timer events allows the workflow to perform tasks or operations within a specified time or time interval, improving the efficiency and accuracy of the workflow.
Use timer events to handle the following situations:
1. Delayed task triggering: If you need to automatically trigger a certain task after a certain period of time, such as automatically sending an email after 1 hour, you can use a timer event to achieve it.
2. Periodic task triggering: If you need to automatically trigger a certain task or operation periodically, such as executing a certain operation regularly every day, you can use timer events to achieve it.
3. Workflow scheduling: If you need to schedule and manage the tasks or operations in the workflow, such as monitoring the execution time of tasks or adjusting the execution order of tasks, you can use timer events to achieve.
It should be noted that when using timer events, the configuration of the timer must be accurate and clear, and the corresponding business logic requirements must be met to ensure the correctness and maintainability of the workflow. At the same time, it is also necessary to select an appropriate timer type according to the actual situation, such as based on date, time interval, or CRON expression.
