Sam Tunnicliffe updated CASSANDRA-14802:
----------------------------------------
Status: Patch Available (was: Open)
The {{BOOTSTRAP_REPLACE}} case is, I think, relatively straightforward to fix.
As this is fairly simple to reason about/implement/test, IMO we could consider
it for 4.0 and defer the more complex general case for now. This isn't a new
regression and getting it right (& validating it) is going to be quite
involved, so it feels a bit of a risk for the 4.0 timeframe.

> This might be a good thing, but should probably be configurable, and made
> consistent. Presently, in a number of circumstances where there are multiple
> range movements, {{calculatePendingRanges}} will assign a pending range to a
> node that will not ultimately own it. If done consistently, this might make
> range movements resilient to node failures / aborted range movements, since
> all nodes will be receiving all ranges they might own under any incomplete
> range ownership movements. But done inconsistently it seems only to reduce
> availability in the cluster, by potentially increasing the number of pending
> nodes unnecessarily.
