Steven Hawkins resolved TEIID-2931.
-----------------------------------
Resolution: Done
Switched full outer equi joins to use a single pass and the same buffering as a left outer
join.
Perform equi-join full outer joins in a streaming manner
--------------------------------------------------------
Key: TEIID-2931
URL:
https://issues.jboss.org/browse/TEIID-2931
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.7.1, 8.8
A pass to compute the right outer matches is only needed when there is non-equi join
criteria, since we'll already have determined the right outer values that fail to
match the equi-join predicates on the first pass. Note that second passes are limited
only to the match regions, but we don't have effective buffering logic for that so we
just fully buffer each side.
