Cached plans are too big - can cause out of memory errors --------------------------------------------------------- Key: TEIID-81 URL: https://jira.jboss.org/jira/browse/TEIID-81 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 6.x Reporter: Steven Hawkins Fix For: 6.1.0 Defect Tracker #12381: Running the coper load tests led to this conclusion: Each cached plan takes on average 31 KB of memory. At 140 unique queries / connection and 128 connection this requires over 550 MB of memory just for the plan cache. Half of the memory was consumed by char[]. Over 10% of the memory was used by ElementSymbol objects.
