    Description: 
In Flink streaming API, we do not have any in-built window trigger(s) available for the below use
cases:
 1. DelayTrigger: Window function should trigger in case the 1st element belonging to this
window arrived more than maxDelay(ms) before the current processing time.

2. DelayAndCountTrigger: Window function should trigger in case the 1st element belonging
to this window arrived more than maxDelay(ms) before the current processing time or there
are more than maxCount elements in the window.
