Summary: CEP-15: (C*) Unique Per-Node Id for (Time)UUID (was: CEP-15: (C*) Unique Per-Node Id)

> Key: CASSANDRA-17100
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17100
> Project: Cassandra
> Issue Type: Sub-task
> Components: Accord
> Reporter: Benedict Elliott Smith
> Priority: Normal
>
> Negotiate a unique and persistent id for each node on joining the cluster that is sufficiently compact to use for the node part of a v2, v6 or v8 (Time)UUID, i.e. it should be at most 48 bits in length. In practice we should be able to target 7, 14 or 21 bits in length depending on cluster size, permitting more efficient vint encoding over the network and on disk.
