Subject RE: Predicate Pushdown in Drill

Thanks Robert for sharing documents.

But there is no input on predicate pushdown support for join queries.


So I am assuming that Drill still does not support any predicate pushdown with simple or complex
join queries against single data store or 

against multiple federated data stores.

There is some information in the docs:








I don't believe we push predicates past a join.

Does Drill support predicate pushdown when executing join queries against single datastore
or against multiple federated datastores?




If yes, can you share more inputs on how Drill supports Predicate Pushdown for inner join,
outer join and self-join queries.
