-------------------------------------------
Summary: BatchLogManager shouldn't serialize mutations with
version 1.2 in 2.1.
Key: CASSANDRA-6931
URL: https://issues.apache.org/jira/browse/CASSANDRA-6931
Project: Cassandra
Issue Type: Bug
Reporter: Sylvain Lebresne
Assignee: Aleksey Yeschenko
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.
