> Project: Hive
> Issue Type: Bug
> Components: Materialized views
> Reporter: Krisztian Kasa
> Assignee: Krisztian Kasa
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.1.0
>
>
> To support incremental rebuild of materialized views which definition does
> not have aggregate in presence of delete operations in any of its source
> tables the records of the source tables need to be uniquely identified and
> joined with the records present in the view.
> One possibility is to project ROW_IDs of each source table in the view
> definition but the writeId component is changing at delete.
> Another way is to project columns of primary keys or unique keys but these
> constraints are not enforced in Hive.
