Steven Hawkins resolved TEIID-2120.
-----------------------------------
Resolution: Done
When moving ahead to the next batch we have to check to see if we're in a match region and save the batch for potential re-reading.

> Key: TEIID-2120
> URL: https://issues.jboss.org/browse/TEIID-2120
> Project: Teiid
> Issue Type: Bug
> Components: Query Engine
> Affects Versions: 7.1
> Reporter: Steven Hawkins
> Assignee: Steven Hawkins
> Priority: Critical
>
> If a save on mark batchiterator reads through a batch in a mark state it will not be saved to the buffer and then not be available for re-reading.
> This specifically affects the right side of already sorted non-full outer merge joins with match regions that are sufficiently large to span batches.
