Hi Robert. I just did a test (shutdown all nodes, start one non-seed node.)
You're correct that an old non-seed node can start by itself. So startup scripts don't have to be intelligent, but apps need to wait until there's enough nodes up to serve the whole keyspace: cqlsh:my_keyspace> consistency Current consistency level is ONE. cqlsh:my_keyspace> select * from numbers where v=1; v --- 1 (1 rows) cqlsh:my_keyspace> select * from numbers where v=2; Unable to complete request: one or more nodes were unavailable.
