Ariel Weisberg commented on CASSANDRA-13704:
--------------------------------------------
Should we also handle when we receive a read request for a range we are pending
for? We shouldn't answer such queries?
> Better handling of out of range tokens

> Key: CASSANDRA-13704
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13704
> Project: Cassandra
> Issue Type: Bug
> Components: Coordination, Observability
> Reporter: Sam Tunnicliffe
> Priority: Major
>
> It is possible for nodes to have a divergent view of the ring, which can
> result in some operations being sent to the wrong nodes. This is an umbrella
> ticket to mitigate such issues by adding logging when a node is asked to
> perform an operation for tokens it does not own. This will be useful for
> detecting when the nodes' views of the ring diverge, which is not highly
> visible at the moment, and also for post-hoc analysis.
> It may also be beneficial to straight up reject certain operations, though
> this will need to balance the risk of performing those ops against the
> consequences rejecting them has on availability.
