Summary: Toughen up column drop/recreate validations in 3.0/3.11
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
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.
