The WAL (and walls in general) impose a performance overhead.
If one were to just take a machine out of the cluster, permanently, when a
machine crashes, you could quickly get all the shards back up to N replicas
after a node crashes.
So realistically, running with a WAL is somewhat redundant.
Well... it depends. Are you saying whenever a machine dies, or any
reason, you'd bootstrap a new one in it's place? Or do you just not care
about the data?
There are cases where it might be ok (if you're using Cassandra as a cache)
but if it's your source of truth I think this is likely to
