Stefania updated CASSANDRA-12705:
---------------------------------
Assignee: Stefania
Status: Patch Available (was: Open)
> Add column definition kind to system schema dropped columns
> -----------------------------------------------------------
>
> Key: CASSANDRA-12705
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12705
> Project: Cassandra
> Issue Type: Bug
> Components: Distributed Metadata
> Reporter: Stefania
> Assignee: Stefania
> Fix For: 4.0
>
>
> Both regular and static columns can currently be dropped by users, but this
> information is currently not stored in {{SchemaKeyspace.DroppedColumns}}. As
> a consequence, {{CFMetadata.getDroppedColumnDefinition}} returns a regular
> column and this has caused problems such as CASSANDRA-12582.
> We should add the column kind to {{SchemaKeyspace.DroppedColumns}} so that
> {{CFMetadata.getDroppedColumnDefinition}} can create the correct column
> definition. However, altering schema tables would cause inter-node
> communication failures during a rolling upgrade, see CASSANDRA-12236.
> Therefore we should wait for a full schema migration when upgrading to the
> next major version.
