> Key: CASSANDRA-15204
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15204
> Project: Cassandra
> Issue Type: Bug
> Components: Cluster/Schema
> Reporter: Aleksey Yeschenko
> Assignee: Aleksey Yeschenko
> Priority: Normal
>
> After CASSANDRA-8099 it’s no longer possible to safely drop/add columns with
> incompatible types. In 4.0 we validate this correctly, but in 3.0 we don’t,
> and that can result in unreadable sstables (corrupted serialization headers
> causing simple columns to be read as complex or vice versa).
> This patch brings 3.0 in line with 4.0 restrictions, making such corruption
> impossible.
