[ https://issues.jboss.org/browse/DROOLS-41?page=com.atlassian.jira.plugin.... ] Lorenzo Melegari updated DROOLS-41: ----------------------------------- Steps to Reproduce: You can find sample code in https://github.com/lome/lome_intext Sample codes insert 1K Myfacts/seconds and aggregates them using the following rule: rule "Dummy" timer( cron:0/5 * * * * ? ) when Number( $count : intValue ) from accumulate( MyFact( ) over window:time(5s) from entry-point EventStream, sum(1) ) then System.out.println($count+" myfact(s) seen in the last 5 seconds"); end After a while, the process goes out of memory. [Profiler Screenshot|https://raw.github.com/lome/lome_intext/master/DroolsIssueWind...] [Profiler Memory Inspect|https://raw.github.com/lome/lome_intext/master/DroolsIssueWindow_...] As comparison, using the same event injector, this rule was also used: declare MyFact @role( event ) @timestamp( timestamp ) @expires( 5s ) end rule "Dummy" timer( cron:0/5 * * * * ? ) when Number( $count : intValue ) from accumulate( MyFact( ) from entry-point EventStream, sum(1) ) then System.out.println($count+" myfact(s) seen in the last 5 seconds"); end Reaching the same result of aggregating over a fixed time window, but, this time, the memory consumption and usage turns out to be way better [Profiler Screenshot|https://raw.github.com/lome/lome_intext/master/DroolsIssue_NoW...] [Profiler Memory Inspect|https://raw.github.com/lome/lome_intext/master/DroolsIssueNoWindo...] was: You can find sample code in https://github.com/lome/lome_intext Sample codes insert 1K Myfacts/seconds and aggregates them using the following rule: rule "Dummy" timer( cron:0/5 * * * * ? ) when Number( $count : intValue ) from accumulate( MyFact( ) over window:time(5s) from entry-point EventStream, sum(1) ) then System.out.println($count+" myfact(s) seen in the last 5 seconds"); end After a while, the process goes out of memory.
