> Right now, if hinted_handoff_enabled is set to false, it stops new Hinted Handoffs from
being written, but the existing ones are still being sent. I believe this is incorrect.
> On our cluster, we have disabled Hinted Handoffs, and a week later they are still being
sent to other nodes, and are still being compacted. This clearly is not the desired behavior.
I cannot think of a scenario when one would want to keep receiving Hinted Handoffs after explicitly
turning them off. By turning them off, you've already stated that some data loss and inconsistency
is acceptable.
> A more aggressive strategy would be to remove from disk all the HintsColumnFamily* files
on startup, if Hinted Handoffs were turned off. This would prevent them from being sent, and
the existing ones from still being compacted.
