Aleksey Yeschenko commented on CASSANDRA-6505:
----------------------------------------------

Pushed https://github.com/iamaleksey/cassandra/commits/6505-v2, with the nits 
addressed and lots of (unnecessary) changes reverted. You should be sleeping 
better with this version.

For the record - the changes in the original 6505 are there b/c I took the code 
more or less directly from the 6504 branch. And it was created before 
CASSANDRA-6506 was in plans, so if we were going to keep CounterContext, I 
wanted it to at least be decently rewritten.

> CASSANDRA-6504 introduces a new type of shard - 'global' - to 2.1. To enable 
> live upgrade from 2.0 to 2.1, it's necessary that 2.0 nodes are able to 
> understand the new 'global' shards in the counter contexts.
> 2.0 nodes will not produce 'global' shards, but must contain the merge logic.
> It isn't a trivial code change ("non-trivial code in a non-trivial part of 
> the code"), hence this separate JIRA issue.
