What would be the most efficient way to get notified when results of a specific query have changed?


Clara computes query results upfront; when you call (query session ….) you’re basically just doing map lookups. So I don’t think different ways of doing this would have much difference in terms of performance; you’d probably want something that stores the previous state, calls query on the session, and then compares them.


I was thinking more in terms of getting notified per query only when the results changed. I'll look at doing it with a listener.
