Ben-Zvi commented on issue #1738: DRILL-7062: Initial implementation of
run-time row-group pruning
URL: https://github.com/apache/drill/pull/1738#issuecomment-482479842
The code has been modified, simplified and passes all the tests. The changes
from the first PR:
(a) Cancelled item (4) above (new ctor for ParquetGroupScan).
(b) Pass the TupleSchema thru the plan API, and use it to construct the
FilterPredicate outside the runtime FOR loop.
(c) Reduction of any unneeded new object construction and other work inside
the FOR loop. E.g., only allocate metadata for the "interesting" columns.
(d) Undid most of the footer passing thru the Metadata API (item (8-b)
above).
(e) Solved the issue with the Hive Drill Native Scan, thus RTP is no longer
disabled in that case (item (1) above)
