certainly be more control than just
increasing or decreasing the number of tokens assigned to a node.

For OPP the problem of load balancing is more profound. Now you need
vnodes per keyspace because you can not expect each keyspace to have
the same distribution. With three keyspaces you are not unsure as to
which was is causing the hotness. I think OPP should just go away.
That's a good
trivial. The only
additional change needed is to assign the tokens in some other way
which does not restrict the ranges to being contiguous.

May be, what i mean is little more simple than that... We can consider
every node having a multiple

, 4125, 4127, 4123 as a group.
From what I've seen, review should proceed fairly quickly, so
hopefully floating the earlier ones a bit longer won't add much pain.
Agreed, that makes sense.

Hello cassandra-dev,
I would like to continue the momentum on improving Cassandra's tracing,
following Mick's excellent work on pluggable tracing and Zipkin support.
There are a couple of areas we can improve that would make tracing an even
more
useful tool for cluster operators to diagnose
