> Key: CASSANDRA-10723
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10723
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Robert Stupp
> Priority: Minor
>
> (Follow-up to CASSANDRA-10721)
> In order to re-write an INITCOND value when a UDT is changed (component
> renamed or type altered), we will have to check for broken aggregates first
> (as we do not know why _exactly_ these are broken; CASSANDRA-10721 added
> {{Function.isBroken()}}).
> If one of the affected aggregates is broken, the request *must fail*.
> If none of the affected aggregates is broken, we can re-write the binary
> representation of the INITCOND and push schema migrations for these
> aggregates.
> Still unclear, if the user needs permissions on both the UDT _and_ the
> affected UDAs for that.
> Further, the UDT change and all UDA changes should be migrated in a single
> mutation, which feels to be the biggest change. This is not a strict
> requirement but would keep that schema change atomic.
