> BatchLogManager serialize and deserialize mutations using MessagingService.VERSION_12 and this is hardcoded. Meaning that it does that in 2.0, 2.1 and trunk, even though in 2.1 the 1.2 format is not properly serialized properly since [this commit|https://github.com/apache/cassandra/commit/cca65d7c1638dcd9370b080f08fd55faefc2733e] (meaning that I'm pretty sure batch logs on super columns is broken on 2.1 currently). And keeping the 1.2 format indefinitely just for batchlog is unrealistic.
> So batchlog needs to do something like hints, record the messaging format used to encode every mutation and use that for deserialization, but always serialize with the current format.
