Smaller initial memory buffer allocations ----------------------------------------- Key: TEIID-5534 URL: https://issues.jboss.org/browse/TEIID-5534 Project: Teiid Issue Type: Quality Risk Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Major Fix For: 12.0, 11.2.1 For smaller vms, under 16 GB, the default allocation scheme for on-heap fixed memory buffers is in 1 GB increments. This can be quite large for VMs under 8 GBs - especially if the full commit of that memory is not needed. The allocation scheme should introduce the buffers more incrementally and release them when compaction is run if they aren't needed.
