Steven Hawkins resolved TEIID-2707.
-----------------------------------
Resolution: Done
Rewrote the prefetch logic to be more straight-forward and covered additional cases. Also
removed the use of the prefetch limit and instead made it based upon the number of batches
pulled from the other side. Will update the docs that the property is not currently
used.
proactive buffering on an enhanced sort merge left outer join results
in an assertionerror
------------------------------------------------------------------------------------------
Key: TEIID-2707
URL: https://issues.jboss.org/browse/TEIID-2707
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 8.4
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.4.1, 8.6
The proactive buffering logic with particular blocking patterns is not correct. Namely
the setting of the buffer to forward only prevents re-reading which results in an
AssertionError.
