Johnathon Lee created TEIID-2363: ------------------------------------ Summary: proactive buffering not occurring for the inner side of an outer join on "MERGE JOIN (SORT/ALREADY_SORTED)" Key: TEIID-2363 URL: https://issues.jboss.org/browse/TEIID-2363 Project: Teiid Issue Type: Feature Request Components: Query Engine Affects Versions: 7.7.2 Reporter: Johnathon Lee Assignee: Steven Hawkins The issue here is this is an outer join and the inner side (the already sorted side) will be buffered regardless. Current logic does not catch blocked exceptions from one side and pro-actively buffer the other - rather we are serially performing the sort and then continue with the loading of the inner side There is a clear trade-off between execution speed and buffering so this behavior may have to be hint or config driven. -- This message is automatically generated by JIRA.
