Yes. The intent is that after the drain your commitlog is empty (e.g. for upgrading to 0.7). If it were to continue to accept writes that would not be the case. If you just want a flush, run `nodetool flush`. -- Jonathan Ellis Project Chair, Apache Cassandra co-founder of Riptano, the source for professional Cassandra support http://riptano.com
