Jonathan Ellis commented on CASSANDRA-4543:
-------------------------------------------
After a batchlog entry (CASSANDRA-4542) is written, if it isn't removed within
2*rpc_write_timeout, we should be fairly safe in assuming that the coordinator
failed and the batch will need to be replayed. (If in fact the coordinator is
still alive but degraded, replaying it will be idempotent and harmless.)
Suggest leveraging the existing hint mechanism for replay: turn the batch entry
into its component mutations, hint those, and let HHOM replay when the target
is alive.
