Jesus Camacho Rodriguez commented on HIVE-10459: ------------------------------------------------ [~thai.bui], would you mind to send your question to mailing list and we can continue discussion over there? Thanks I am going to close this issue as initial work for implementing materialized views support has been mostly completed. Documentation can be found in: https://cwiki.apache.org/confluence/display/Hive/Materialized+views > Add materialized views to Hive > ------------------------------ > > Key: HIVE-10459 > URL: https://issues.apache.org/jira/browse/HIVE-10459 > Project: Hive > Issue Type: New Feature > Components: Views > Reporter: Alan Gates > Assignee: Jesus Camacho Rodriguez > Priority: Major > Fix For: 3.2.0 > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
