-------------------------------------
Summary: Large sort performance
Key: TEIID-2429
URL: https://issues.jboss.org/browse/TEIID-2429
Project: Teiid
Issue Type: Quality Risk
Components: Query Engine
Affects Versions: 7.4
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.4
Large sorts (high data volume over above several hundred thousand rows) experience a disproportionate performance degradation as the data set grows larger.
This is due to the SortUtility default collection strategy that will create intermediate sort buffers too proactively.
