Subject Re: Which version is stable enough for production environment?
Date Fri, 02 Dec 2016 13:21:46 GMT
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.
