Subject How know node is fully up?
Date Fri, 18 Dec 2009 18:33:43 GMT
How can i tell that a node is completely up and taking reads and writes?

- at startup?
- after new bootstrap?
- after a node has been unavailable for some time and rejoins the cluster?

i see the "INFO [main] [] Cassandra starting up..." message in the
log, but it seems to have happened way too fast after i simulated a crash.

using tpstats i don't see any ROW-READ-STAGE completed, but lots of ROW-MUTATION-STAGE completed
which seems to be correct for a node that is still sync'ing with the cluster after being unavailable.

.. but how do i know ;)
