Jonathan Ellis updated CASSANDRA-3564:
--------------------------------------
Description:
Cassandra handles flush in its shutdown hook for durable_writes=false CFs
(otherwise we're *guaranteed* to lose data) but leaves it up to the operator
otherwise. I'd rather leave it that way to offer these semantics:
- cassandra stop = shutdown nicely [explicit flush, then kill -int]
- kill -INT = shutdown faster but don't lose any updates [current behavior]
- kill -KILL = lose most recent writes unless durable_writes=true and batch
commits are on [also current behavior]
But if it's not reasonable to use nodetool from the init script then I guess we
can just make the shutdown hook flush everything.
