John Sichi updated HIVE-1941:
-----------------------------
Status: Open (was: Patch Available)
Improvement needed from code review session at Facebook:
* ALTER VIEW ADD/DROP PARTITION needs to derive dependencies on underlying
table partitions in order for replication to work (report them via hook
input/outputs)
Followups needed:
* Store partition-level dependencies in metastore; use these later for stuff
like retrieving stats from underlying table partitions
* CREATE OR REPLACE VIEW to avoid having to drop all partitions during schema
evolution
* For a join view with join on partition column, optimizer should be smart
enough to push predicate down both ways in order to avoid errors in strict mode
(investigate whether this is already happening)
> support explicit view partitioning
