If you can change to 8 vnodes, it will be much better for repairs and other kinds of streaming operations. The old advice of 256 per node is now not very helpful.

Do you use vnodes? How many vnodes per machine?

We are planning to add a third datacenter to our cluster (already has 2 datacenter, every datcenter has 50 nodes, so 100 nodes in total).


My fear is that an important number of nodes per cluster (> 100) could cause a lot of problems like gossip duration, maintenance (repair...)...


I know that it depends on use cases, volume of data and many other thing, but I would like that you share your  experiences with that.
