Hi,
I would say that i agree with Jon, Jeff and Alain at the same time ;-)
Basically you should be very comfortable to do it for conf, cassandra
version or Os update but not because if you not do it your cluster starts
suffering from performance issues or something like that. If so, you should
I agree with Jeff here. Ideally you should be so comfortable with rolling
restarts that they become second nature. Cassandra is designed to handle
them and you should not be afraid to do them regularly.

If you see latencies jump or timeouts when you’re bouncing, that’s a warning
Great!
Thank you very much Alain!

they are memory issues/leaks or something like that, going wrong, but
'normally', you should not have to do that. Even more, when doing

cluster once in a while.
Is it a good practice or necessary? how often?
Thanks
