Steven Hawkins updated TEIID-2931:
----------------------------------
Summary: Perform equi-join full outer joins in a streaming manner (was: Perform
equi-join full outer joins in a single pass)
Description: 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. (was: 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.)
