>             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.
