Fire and Purge with Idle State


Say im aggregating an event stream by sessionId in SQL and im emitting the
results once the session is "over", i guess i should be using Fire and Purge
- i dont expect to need to session data once over. How should i treat the
Idle state retention time - is it needed at all if im using purge? will it
become relevant only if a session is both never-ending AND never has more
