Aditya Kishore updated DRILL-494:
---------------------------------
Description: For example, HBase storage plugin could add a rule which would
transform an HBase scan followed by a qualified filter operation into an HBase
scan with an HBase filter pushed directly to the scan operation. (was:
Presently, a condition clause in a SQL query results in a filter operation
after scan (or project). However with some storage engines may support pushing
down (a part of) these filters as a parameter to scan.)
