Subject partitioned views
Date Wed, 09 Feb 2011 23:29:13 GMT
One of the impediments for uptake of the CREATE VIEW feature in Hive has been the lack of partition
awareness.  This made it non-transparent to replace a table with a view, e.g. for renaming
purposes.  To address this as well as some other use cases, I'm proposing the first steps
towards view partition support:

This solution is still primitive, but should make using views at least possible in a number
of cases, with a bit of extra DDL/ETL effort.

Feedback welcome.
