Resolution: Duplicate
> UDF use new schema migration
> ----------------------------
>
> Key: CASSANDRA-7697
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7697
> Project: Cassandra
> Issue Type: Bug
> Reporter: Robert Stupp
> Assignee: Robert Stupp
> Fix For: 3.0
>
>
> UDF is the "prototype candidate" for new, fine granular schema migration.
> On the basic level, everything stays the same, more or less, except:
> # We might use separate versioning for migration messages (in addition to the
> messaging version)
> # For DROP X changes, we only encode what's necessary (the keyspace name, the
> table name, the timestamp). Not to save bytes, but to avoid going through a
> full schema merge on the node.
> # Include the type of change with all other schema changes, for the same
> reason.
> # For schema pulls, use a merkle tree or something similar, to only
> pull/apply the relevant changes.
