Jonathan Ellis commented on CASSANDRA-8494:
-------------------------------------------
ISTM that there is some commonality here with nodes telling the cluster "I've
lost a disk so I don't have vnodes X Y and Z" post-CASSANDRA-6696. So a
bootstrapping node would tell the cluster that initially it has nothing, and
would update as we add the different vnodes in.

> Current bootstrapping involves (to my knowledge) picking tokens and streaming
> data before the node is available for requests. This can be problematic with
> "fat nodes", since it may require 20TB of data to be streamed over before the
> machine can be useful. This can result in a massive window of time before
> the machine can do anything useful.
> As a potential approach to mitigate the huge window of time before a node is
> available, I suggest modifying the bootstrap process to only acquire a single
> initial token before being marked UP. This would likely be a configuration
> parameter "incremental_bootstrap" or something similar.
> After the node is bootstrapped with this one token, it could go into UP
> state, and could then acquire additional tokens (one or a handful at a time),
> which would be streamed over while the node is active and serving requests.
> The benefit here is that with the default 256 tokens a node could become an
> active part of the cluster with less than 1% of it's final data streamed over.
