[ https://issues.jboss.org/browse/TEIID-2169?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-2169: --------------------------------------- Based upon https://community.jboss.org/thread/178102 and several INSP issues about memory pressure eviction, this is not something that we can currently do or even address in the near term. The eviction strategy is not customizable and the eviction queue is not accessible (the Eviction is not accessible from a Segment and the queue is not accessible from the Eviction). The core issue here is whether the LFRU imposes too much overhead vs. LIRS. We should do some performance tests on hit ratios and overhead to see if we need to push this feature into INSP. Ideally the entire strategy could be implemented with INSP, however they have already rejected the use of NIO managed direct memory with the possible inclusion of JNI accessed current maps from intel c libraries. There again it could be evaluated whether adapting Teiid's existing use of direct memory (which isn't quite complete as keys are still held on heap and would need to be adapted for chained eviction) could be beneficial. -- This message is automatically generated by JIRA.
