Jonathan Ellis commented on CASSANDRA-4017:
-------------------------------------------
bq. More precisely, SchemaLoader was not using the migration path, but only
loading the schema in-memory. Because the patch removes the local special case,
this was breaking DefsTest.
Why can't we still call {{Schema.load(KSMetaData)}} directly?

> Now that we can send a schema as a RowMutation, there's no need to keep
> separate add/drop/update migration classes around. Let's just send the
> schema to our counterparts and let them figure out what changed. Currently
> we have "figure out what changed" code to both generate migrations on the
> sender, and for application on the target, which adds complexity.
