-------------------------------------------
Summary: Better reporting of events for out of range tokens
Key: CASSANDRA-13704
URL: https://issues.apache.org/jira/browse/CASSANDRA-13704
Project: Cassandra
Issue Type: Improvement
Components: Coordination, Observability
Reporter: Sam Tunnicliffe
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.
