Any insights on vnodes, one month after my original post ?

Hi, 

Adding vnodes is a big improvement to Cassandra, specifically because we have a fluctuating load on our Cassandra depending on the week, and it is quite annoying to add some nodes for one week or two, move tokens and then having to remove them and then move tokens again. Even more if we could automate some up-scale thanks to AWS alarms, It would be awesome.

We don't use vnodes yet because Opscenter did not support this feature and because we need to have a reliable production. Now Opscenter handles vnodes.

Are the vnodes feature and the tokens =>vnodes transition safe enough to go live with vnodes ?

What would be the transition process ?

Does someone auto-scale his Cassandra cluster ?

Any advice about vnodes ?
