What are some common use cases for TickTuple in Storm?

In Storm, the TickTuple is a special tuple used to trigger the processing logic of a bolt at regular intervals. Common use cases include:

1. Heartbeat monitoring: Using TickTuple to regularly send a heartbeat signal to the bolt to confirm if the bolt is in normal running status.
2. Scheduled triggering: You can use TickTuple to trigger certain operations on a regular basis, such as cleaning cache or performing regular data analysis.
3. Control flow: The execution sequence can be controlled using TickTuple, such as triggering certain operations at specific time points.

In general, the common use case of TickTuple in Storm is to trigger timing events and control the execution of processes. By sending TickTuple, scheduling timed tasks and controlling processes can be achieved, enhancing the flexibility and reliability of Storm topologies.
