Hi, Does Cassandra support rolling restart recipe between minor version upgrade? I mean rolling restart is a way to upgrade Cassandra version or change configuration **without** bringing down the whole cluster. The recipe will be something like killing a couple of nodes at a time and starting them again with newer version (or newer configuration.)
To make this possible, I think at least the RPC and SSTable format should be compatible between older and newer versions. Do you have any plan to change them in the future? Also, there might be some exceptions and certain combinations of versions can't coexist in a cluster (e.g. RPC or SSTable bug in the older version.) It will be great if such incompatibilities are documented in the release note. Thanks, Tatsuya -- Tatsuya Kawano (mr.) Tokyo, Japan
