Re: [rules-users] Drools memory consumption

Thanks for the valuable feedback! Regarding remarks about the rule itself: > a) Each Log without a CorrelatedEvent creates an activation. A > CorrelatedEvent will not apear until there are 20 Logs with the same > src/dst combination. This means that there are up to 19 pending > accumulates until the first > one reaches the threshold, inserts the CorrelatedEvent and cancels the > others. How can I make more efficient?

I tried to remove accumulation of the markers. These are the changes: New function: function Set getMarkers(Set matchedLogs) { HashSet<String> markerSet = new HashSet<String>(); HashSet<String> idSet = new HashSet<String>(); for (Object matchedLogObj : matchedLogs) { Log matchedLog = (Log) matchedLogObj; String id = getUniqueId(matchedLog); if (!idSet.contains(id)) { idSet.add(id); markerSet.add(matchedLog.fieldsMap.get("marker").toString()); if (markerSet.size() == 25) break; } } return markerSet; } In LHS: accumulate($accumulatedLog : Log(eval(filter($accumulatedLog)), this after[0s,60s] $log, fieldsMap.get("src") == $log.fieldsMap.get("src"), fieldsMap.get("dst") == $log.fieldsMap.get("dst"), $id : getUniqueId(this)); $idSet : collectSet($id) , $matchedLogs: collectSet($accumulatedLog); $idSet.size > 19) In RHS: fieldsMap.put("cu_markers_list", getMarkers($matchedLogs)); $matchedLogs return as empty set. Why? How can I make it work?
