Subject Re: Which version is stable enough for production environment?
Date Wed, 30 Nov 2016 08:58:15 GMT
I didn't mean to criticise you. It was meant as a notice for all of those
who are planning to use MVs.

I already made proposals to solve these issues on the dev list and plan to
test them on our own cluster during the next days. I am currently working
heavily on this as we have big trouble bootstrapping new nodes on our 3.10
cluster - due to these known issues.

JFYI.
