----------------------------------------------
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.
