Stefania updated CASSANDRA-12516:
---------------------------------
Status: Patch Available (was: In Progress)
> Interned column identifiers can be overridden incorrectly
> ---------------------------------------------------------
>
> Key: CASSANDRA-12516
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12516
> Project: Cassandra
> Issue Type: Bug
> Reporter: Aleksey Yeschenko
> Assignee: Stefania
> Fix For: 3.0.x, 3.x
>
>
> As discovered by [~Stefania] in CASSANDRA-12423, our use of
> {{ColumnIdentifier.internedInstances}} to map byte buffer column names to
> column identifiers is incorrect. It's possible for two non-equal
> {{ColumnIdentifier}} instances to have the same {{ByteBuffer}} as raw name,
> and yet different text representations, due to different column name types,
> leading to hard to debug correctness issues.
> Should either amend the map to have the type as part of the key, or limit the
> use of that map.
