Subject Re: Predicate Pushdown in Drill
Date Tue, 17 Oct 2017 21:44:16 GMT
There is some information in the docs:


https://drill.apache.org/docs/partition-pruning-introduction/


https://drill.apache.org/docs/parquet-filter-pushdown/

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


Thanks.

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.
