             Summary: Add simple materialized views with manual rebuilds
                 Key: HIVE-14249
                 URL: https://issues.apache.org/jira/browse/HIVE-14249
             Project: Hive
          Issue Type: Sub-task
          Components: Parser, Views
            Reporter: Alan Gates
            Assignee: Alan Gates


This patch is a start at implementing simple views. It doesn't have enough testing yet (e.g.
there's no negative testing). And I know it fails in the partitioned case. I suspect things
like security and locking don't work properly yet either. But I'm posting it as a starting
point.

In this initial patch I'm just handling simple materialized views with manual rebuilds. In
later JIRAs we can add features such as allowing the optimizer to rewrite queries to use materialized
views rather than tables named in the queries, giving the optimizer the ability to determine
when a materialized view is stale, etc.

Also, I didn't rebase this patch against trunk after the migration from svn->git so it
may not apply cleanly.
