[teiid-issues] [JBoss JIRA] Resolved: (TEIID-1463) limit buffering for large results

Steven Hawkins resolved TEIID-1463.
-----------------------------------
Labels: performance (was: )
Resolution: Done
non-cached forward-only results will limit their buffers to 20 batches and block until the
client pulls more results. If client processing of results lags for large results, there
is a potential for resources to be held open - but disk resources will not be proactively
consumed, which can be problematic in million row scenarios.
limit buffering for large results
---------------------------------
Key: TEIID-1463
URL: https://issues.jboss.org/browse/TEIID-1463
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Affects Versions: 7.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Labels: performance
Fix For: 7.4
In a forward only scenario, if a client lags behind the server a buffer will still be
built containing much of result. It would be good to limit the buffer size and prempt
proactive processing when exceeded.
