[teiid-issues] [JBoss JIRA] Resolved: (TEIID-761) Correct inefficient buffermanager tuplesource and managedbatch scans

Correct inefficient buffermanager tuplesource and managedbatch scans -------------------------------------------------------------------- Key: TEIID-761 URL: https://jira.jboss.org/jira/browse/TEIID-761 Project: Teiid Issue Type: Quality Risk Components: Query Engine Affects Versions: 6.0.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 6.2.0 MemoryState should hold ManagedBatches in a linkedhashset rather than a list so that explicit management of last access is unnecessary and the removal call performs better than a linear search. Removetuplesources should be changed to use an explicit set of tuplesources on the tuplegroupinfo rather than doing a linear scan of all tuplesources.
