Andrés de la Peña updated CASSANDRA-12952:
------------------------------------------
Fix Version/s: 4.x
> AlterTableStatement propagates base table and affected MV changes inconsistently
> --------------------------------------------------------------------------------
>
> Key: CASSANDRA-12952
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12952
> Project: Cassandra
> Issue Type: Bug
> Components: Distributed Metadata, Materialized Views
> Reporter: Aleksey Yeschenko
> Assignee: Andrés de la Peña
> Fix For: 3.0.x, 3.11.x, 4.x
>
>
> In {{AlterTableStatement}}, when renaming columns or changing their types, we also keep
track of all affected MVs - ones that also need column renames or type changes. Then in the
end we announce the migration for the table change, and afterwards, separately, one for each
affected MV.
> This creates a window in which view definitions and base table definition are not in
sync with each other. If a node fails in between receiving those pushes, it's likely to have
startup issues.
> The fix is trivial: table change and affected MV change should be pushed as a single
schema mutation.
