Re: [rules-users] Drools memory usage issue

Hi, We have an drools 5.0.1 application that uses StatelessSession and high volume of objects (facts) that we need to apply static rules on, and having out of memory issues doing so. We added the following three properties as given in the drools documentation for decreasing the memory usage: drools.shadowproxy=false drools.maintainTms=false drools.sequential=true As per the following blog, there is an algorithm to minimize the engine work, and memory usage. http://blog.athico.com/2007/07/sequential-rete.html Are the properties above sufficient to trigger this algorithm, or do we need to do write extra code for this? Also, does the "drools.sequential" property make sure that rules are applied sequentially on facts? If so, is there a hook into the drools engine to figure out which particular rule is consuming more memory or having more execution time? Thanks in advance.
