Subject Re: what happen if coordinator node fails during write
Date Wed, 26 Jun 2013 00:45:56 GMT
It depends on cassandra version. As far as I know in 1.2 coordinator logs
request before it updates replicas. If it fails it will replay log on
startup.
In 1.1 you may have inconsistant state, because only part of your request
is propagated to replicas.

Thank you,
  Andrey
