Re: C* in multiple AWS AZ's


The single node in 1e will be a replica for every range (and you won’t be able to tolerate an outage in 1c), potentially putting it under significant load

I have a 6-node cluster I'm migrating to the new i3 types.
But at the same time I want to migrate to a different AZ.

What happens if I do the "running node replace method" with 1 node at a time moving to the new AZ. Meaning, I'll have temporarily;

5 nodes in AZ 1c
1 new node in AZ 1e.

I'll wash-rinse-repeat till all 6 are on the new machine type and in the new AZ.

Any thoughts about whether this gets weird with the Ec2Snitch and a RF 3?
