Schema evolution rules allow always being able to write with an older schema, so that there is no need to check whether the schema a writer is using is allowed. That cuts down on commit conflicts, but it also means that schemas should always be rolled forward and never backward. I don't think that we want to start adding extra validation to support a case where we roll back a schema. -- This is an automated message from the Apache Git Service.
