Nikolay Vasilishin commented on FLINK-4565:
-------------------------------------------
Thanks, guys.
I've implemented first two cases: disjunctive equality predicates for less then
20 entries and reusable hashset for >= 20 predicates.
Can you give any advice, where I can find anything in code related to 3
subissue? Where is the point in which I can access the subquery results and use
them for IN operator?
