Brandon Williams commented on CASSANDRA-5051:
---------------------------------------------
bq. But is there potential for us to also throw away data that we shouldn't if
we get behind on gossip somehow?
I don't see how. We're fairly well protected by persisting the ring, but even
without that if we're behind, don't we just own more than we should? This was
the impetus for persisting the ring.
> Allow automatic cleanup after gc_grace

> When using vnodes, after adding a new node you have to run cleanup on all the
> machines, because you don't know which are affected and chances are it was
> most if not all of them. As an alternative to this intensive process, we
> could allow cleanup during compaction if the data is older than gc_grace (or
> perhaps some other time period since people tend to use gc_grace hacks to get
> rid of tombstones.)
