Aleksey Yeschenko commented on CASSANDRA-9200:
----------------------------------------------
With a fixed size ring that we have, and nodes having explicit tokens assigned,
can there be any way to project the token ring to a smaller-cardinality ID
ring, and use tokens to map nodes to their pre-assigned blocks?
Really not a fan of using LWT to pre-allocate blocks.

> 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.
