Aleksey Yeschenko commented on CASSANDRA-9200:
----------------------------------------------
bq. WRT to token/partition-scoping, this assumes that the tokens in a cluster
are constant/never change.
It doesn't assume that. It assumed that we properly handle those changes.
CASSANDRA-9667 would probably make it simpler.

> UUIDs are usually the right choice for surrogate keys, but sometimes
> application constraints dictate an increasing numeric value.
> We could do this by using LWT to reserve "blocks" of the sequence for each
> member of the cluster, which would eliminate paxos contention at the cost of
> not being strictly increasing.
