[teiid-issues] [JBoss JIRA] (TEIID-2410) add tuning for lots of active plans

[ https://issues.jboss.org/browse/TEIID-2410?page=com.atlassian.jira.plugin... ] Steven Hawkins updated TEIID-2410: ---------------------------------- Description: When an active plan is not processing it will still be holding memory against the buffer manager reserve count. (was: When an active plan is not processing it will still be holding memory against the buffer manager reserve count. Also even non-active, but not closed plans can still hold their reservation even though a batch may not be held by the workitem.) I made an initial misdiagnosis here. non-active plans are not holding their reserves - even if they are holding a batch for the forward only logic (which seems like we need to account for). The real problem was that with useCallingThread=false and plans that cause output buffer blocking we will not have the proper number of worker threads active, which will slow processing to a crawl as new plans back-up waiting for older plans to finish processing. -- This message is automatically generated by JIRA.
