| [3.11|https://github.com/jasonstack/cassandra/commits/CASSANDRA-13798-3.11] |
The patch is to revert supporting non-pk base column filtering on MV on 3.11 &
trunk. The feature was added in 3.10 and the consequence may have been
overlooked. It's better to revert it in 3.x/trunk, before more users start
using it.
At the same time, I will work on a proper design (eg. multi-timestamp approach
discussed in CASSANDRA-11500 and CASSANDRA-10226) for non-pk base column
filtering and multiple non-pk base column in view pk.

> 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.
