query construct: Unexpected high memory usage and implicit performance degradation whereas query is NOT called
--------------------------------------------------------------------------------------------------------------
Key: JBRULES-3250
URL: https://issues.jboss.org/browse/JBRULES-3250
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-core
Affects Versions: 5.3.0.CR1
Environment: Windows 7
java version "1.6.0_25"
Java(TM) SE Runtime Environment (build 1.6.0_25-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.0-b11, mixed mode)
Reporter: Roman Novak
Assignee: Mark Proctor
Inserting 850,000 facts of one fact type into working memory results in memory usage (and implicitly in performance degradation) related to the count of occurences of the fact in queries.
Note: The queries are NOT called. No Rules are fired.
Memory impact is about 500 MB on heap qith the shown query.
Performance impact was factor 5 (which maybe cannot be observed with this example).
