Jesus Camacho Rodriguez commented on HIVE-10459:
------------------------------------------------

[~alangates], I will move the initial work to HIVE-14249; we can follow-up 
there with anything related to the patch. As there are a few people watching 
this issue, I will use this as the umbrella JIRA for all the work that we will 
do around materialized views implementation.

> Materialized views are useful as ways to store either alternate versions of 
> data (e.g. same data, different sort order) or derivatives of data sets (e.g. 
> commonly used aggregates).  It is useful to store these as materialized views 
> rather than as tables because it can give the optimizer the ability to 
> understand how data sets are related.
