> Minimize time that REBUILD locks the materialized view
> ------------------------------------------------------
>
> Key: HIVE-18387
> URL: https://issues.apache.org/jira/browse/HIVE-18387
> Project: Hive
> Issue Type: Improvement
> Components: Materialized views
> Affects Versions: 3.0.0
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
> Priority: Major
> Attachments: HIVE-18387.01.patch, HIVE-18387.02.patch,
> HIVE-18387.03.patch, HIVE-18387.patch
>
>
> Currently, REBUILD will block the materialized view while the final move task
> is being executed. The idea for this improvement is to create the new
> materialization in a new folder (new version) and then just flip the pointer
> to the folder in the MV definition in the metastore. REBUILD operations for a
> given MV should get an exclusive lock though, i.e., they cannot be executed
> concurrently.
