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. (SEE CASSANDRA-11500,
> [background|https://issues.apache.org/jira/browse/CASSANDRA-11500?focusedCommentId=16119823&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16119823])
> We should step back and re-consider the non-primary-key filtering feature
> together with supporting multiple non-PK cols in MV clustering key in
> CASSANDRA-10226.
