[JBoss JIRA] (WFLY-5921) Locale cache set to simple cache automatically breaks map reduce

In standalone mode Keycloak uses locale-caches, while in clustered mode we use a combination of invalidation caches and distributed caches. In both clustered and non-clustered mode we use map-reduce tasks to delete elements from the cache. > This has worked just fine until the recent change in CR5 where locale-caches are now set to simple-caches (WFLY-5327). As the caches are now automatically set to simple-caches map-reduce is no longer available. There's also no way to prevent this. > IMO the changes from WFLY-5327 should be reverted and instead a new simple-cache element should be added, or a simple-cache=true attribute added to the locale-cache element. > As it stands this change prevents us from upgrading to CR5. -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (DROOLS-1016) Too much memory consumption while running code on drools6.

by Mario Fusco (JIRA)

[ https://issues.jboss.org/browse/DROOLS-1016?page=com.atlassian.jira.plugi... ] Mario Fusco resolved DROOLS-1016. --------------------------------- Resolution: Rejected The increased requirement in term of the occupied permgen space is not caused by the new phreak algorithm, but mainly by the fact that in drools 6 constraints are jitted, i.e. converted in bytecode and then evaluated in compiled mode instead of keep using mvel for each evaluation. You can have finer grained control over the permgen space used by drools setting the "drools.permgenThreshold" system property. This property represents the threshold of PermGen usage (in percentage) above which the engine stops JITting constraints and let them run in interpreted mode. In particular setting this property to 0 will completely turn off this optimization, but I don't suggest you to do so because the performance gain derived from evaluating the constraints in compiled mode is really relevant. My suggestion, at least on the long term, is to migrate to JDK 8 that no longer has a PermGen space separated from the normal heap space. > Too much memory consumption while running code on drools6. > ---------------------------------------------------------- > > Key: DROOLS-1016 > URL: https://issues.jboss.org/browse/DROOLS-1016 > Project: Drools > Issue Type: Bug > Components: core engine > Affects Versions: 6.2.0.Final > Reporter: Vivek Hingorani > Assignee: Mario Fusco > > The memory usage on drools6 is far more then drools 5. Can we run the drools6 code with Rete algorithm? > We recently migrated our project from Drools 5.3.0.Final version to Drools 6.2.0.Final version. In production we can see a significant increase in the memory consumption per node. we are using java 1.7. We increased the permgen space as well for drools6 from 0.5 GB to 1 GB but still the increase is too much. Is there any solution for the same. > Drools5 memory usage was 0.5GB per node with 0.5GB permgen space > Drools6 memory usage is 1.3GB per node with 1GB permgen space. > Node here is a jvm as we are using oracle coherence. > If further details are needed , let me know. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
