to look at the new patch set (#2).
Change subject: [NO ISSUE][COMP] Prevent broadcast hint changes left-outer-join
semantic
......................................................................
[NO ISSUE][COMP] Prevent broadcast hint changes left-outer-join semantic
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
The current way of handling broadcast hint can cause a problem in a
certain case. When we have a subquery with join, the inline subplan rule
will transform it into a left-outer-join. If we have a broadcast hint
for the join and when the broadcast hint applies, we will switch inputs
of the join if that's necessary without checking whether that will break
the semantic of left-outer-join.
