---------------------------------------
Summary: 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.
