ZhaoYang commented on CASSANDRA-13798: -------------------------------------- Updated NEWS.txt and introduced a flag: {{cassandra.mv.filtering.nonkey.columns=false}}. If users "know what they are doing" ,eg. append-only, they could turn on the flag to create MV with non-pk column filtering. > Disallow filtering on non-primary-key base column for MV > -------------------------------------------------------- > > Key: CASSANDRA-13798 > URL: https://issues.apache.org/jira/browse/CASSANDRA-13798 > Project: Cassandra > Issue Type: Bug > Components: Materialized Views > Reporter: ZhaoYang > Assignee: ZhaoYang > > We should probably consider disallow filtering conditions on non-primary-key > base column for Materialized View which is introduced in CASSANDRA-10368. > The main problem is that the liveness of view row is now depending on > multiple base columns (multiple filtered non-pk base column + base column > used in view pk) and this semantic could not be properly support without > drastic storage format changes.
