> Implement incremental rebuild for materialized views (only insert operations
> in source tables)
> ----------------------------------------------------------------------------------------------
>
> Key: HIVE-18839
> URL: https://issues.apache.org/jira/browse/HIVE-18839
> Project: Hive
> Issue Type: Improvement
> Components: Materialized views
> Affects Versions: 3.0.0
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
> Priority: Major
> Labels: TODOC3.0
> Attachments: HIVE-18839.01.patch, HIVE-18839.02.patch,
> HIVE-18839.03.patch, HIVE-18839.patch
>
>
> Implementation will follow current code path for full rebuild.
> When the MV query plan is retrieved, if the MV contents are outdated because
> there were insert operations in the source tables, we will introduce a filter
> with a condition based on stored value of ValidWriteIdLists. For instance,
> {{WRITE_ID < high_txn_id AND WRITE_ID NOT IN (x, y, ...)}}. Then the
> rewriting will do the rest of the work by creating a partial rewriting, where
> the contents of the MV are read as well as the new contents from the source
> tables.
> This mechanism will not work only for ALTER MV... REBUILD, but also for user
> queries which will be able to benefit from using outdated MVs to compute part
> of the needed results.
