DhamoPS opened a new pull request, #3334:
URL: https://github.com/apache/arrow-datafusion/pull/3334
# Which issue does this PR close?
Closes #78 .
# Rationale for this change
Join Predicates which are part of OR expressions of FILTER PREDICATES, were
not pulled properly. Due to that, CROSS JOINs are chosen for those joins
instead of innerjoin and causes query to run longer. Actually TPCH Q19 was
taking more than 2000 sec in my laptop. With Fix, TPCH Q19 is taking ~3 sec.
# What changes are included in this PR?
-- planner.rs::predicates which are part of OR expr also pulled to
Joined predicates if left and right child of OR expr are having the same
predicates.

# Are there any user-facing changes?
No
