These issues exist since the very first implementation of MVs in *ALL* CS versions. If you want to use MVs, you may want to wait until these issues are officially resolved. For testing or pre-prod, you could checkout https://github.com/Jaumo/cassandra/commits/CASSANDRA-12905. I have fixed these issues inofficially and have this version currently running on our own cluster - but no warranties.
If you don't need MVs, you can for example use the Instaclustr 3.7 LTS version as announced earlier in this thread. 2016-12-02 14:11 GMT+01:00 Hugo José Pinto <hugo.pi...@inovaworks.com>: > All, > > Many thanks for this enlightening thread. > > We're about to go live with a client for a pre-production environment, and > must decide on which 3.x version to use.
