[teiid-issues] [JBoss JIRA] Commented: (TEIID-1750) Memory handling improvements

[ https://issues.jboss.org/browse/TEIID-1750?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-1750: --------------------------------------- Changed the buffermanager to only be concerned with the memory state. Changed the buffering algorithm to be a tiered lru, which significantly reduces reads/writes when accessing table structures. the old lru/mru/working set model was specifically designed for tuplebuffers which have a linear insertion and forward iteration model. there will still need to be some tuning made to better support tuplebuffers. tuplebuffers/tables no longer directly hold managedbatches, which reduces the overall memory footprint. This also helps effectively limit the softreference population. put in a rough cut of a block storage scheme. this is likely to be further refined. the code should naturally allow for off-heap direct memory buffers to be used for large vm scenarios. -- This message is automatically generated by JIRA.
