I have made a cluster for a product, using 10 nodes.
However, inflowing traffic to the cluster was not so much as I thought, actually.
So I decided to shrink the cluster from 10 to 5 nodes.
Here is, I found a way, what I’m supposed to do is to remove a node using the function ‘Remove’ in the couchbase console provided.
But I wonder
- how many nodes I could remove from the cluster at once.
- is it related to the value of replicas? (in my case, replicas is 2)
(In details, I mean, is it available to remove nodes over the value of replicas?)
- what point for performance should I take care of if several nodes would be removed. (Let’s suppose to remove 3~4 nodes at once)
Thank you in advance.
