Subject Re: vnode in production

VNodes in production are pretty stable. That being said, I have never heard of anyone doing
a successful "nodetool shuffle”.  A few people have skirted the issue by creating a new
data center with VNodes enabled and replicating the data over.

Hello all,

 

Just wanted to check if anyone has any experiences to share regarding

1.       the stability of vnodes in production

2.       upgrading to vnodes in production

 

We recently upgraded to 1.2.12 in production and were planning to turn on vnodes using the
“adding a new datacenter” method vs using shuffle which seems to be not recommended. It
helps that we were planning to add capacity to our Cassandra ring anyway. Our tests in QA
so far have been good. If we do not upgrade now however, we will have to add the new hosts
normally to the ring, and may not be able to add a new data center at a later point of time.

 

Thanks,

Arindam
