> Key: CASSANDRA-12952
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12952
> Project: Cassandra
> Issue Type: Bug
> Components: Feature/Materialized Views, Legacy/Distributed Metadata
> Reporter: Aleksey Yeschenko
> Assignee: Andrés de la Peña
> Priority: Normal
> Fix For: 3.0.15, 3.11.1, 4.0

> 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.
