Re: [rules-users] Best practice to use heap memory effectively
Using multiple sessions is not applicable, it will just (heavily) increase
memory requirements.
How precise does this have to be?
For instance, counting all events arriving in the interval yyyy-mm-dd
hh:mm requires 24*60 objects EventsPerMinute per 24 hours. You can
keep track on the running total in one single fact. As soon as the
oldest EventsPerMinute becomes older that 24hrs, you retract it and
reduce the running total.
You can reduce the granularity to seconds, if necessary.

So
each event/fact has different 24 hour period. If you take whole picture it
is not fixed.
Simply can we count number of facts/events in a WM in a particular time
using multiple session? So I can call session.dispose() after each
insertion.
thanks.
