Subject [jira] Commented: (HIVE-1609) Support partition filtering in metastore
Date Thu, 02 Sep 2010 21:33:54 GMT

John Sichi commented on HIVE-1609:
----------------------------------

I agree with Carl regarding the parser:  let's move it to ANTLR.  We have too much generated
code checked into Hive already, and we're trying to move away from that.

> The metastore needs to have support for returning a list of partitions based on user
specified filter conditions. This will be useful for tools which need to do partition pruning.
Howl is one such use case. The way partition pruning is done during hive query execution need
not be changed.
