Shrinking an EON cluster from 12 to 6 nodes
We're currently timing the queries for xxx on a 12-node cluster, using 12 shards.
We would like to repeat the tests with 6 and/or 4 nodes, and would like to shrink the cluster not one node at a time, but removing for example 6 in one go.
We were thinking of calling admintools, Advanced Menu -> Cluster Management -> Remove Host(s), followed by terminating 6 nodes from the AWS EON management console.
What is your take on this? is there a more efficient, safer, more elegant or better for any other reason solution?
Thanks for any hints & cheers -
Dieter and Marco
