We have a PRODUCTION Cluster with 3 config servers(recommended) and 4
shards(each a replica set).
We have procured 12 licensed mongod nodes.
My question is, does the 3 config servers need to be licensed mongod nodes?
According to the 10gen site, config servers are NOT a part of licensed
mongod nodes, however i remember having come across some blog where
licensed mongod node is recommended for config server?
Please let me know thoughts at the earliest as this is URGENT.
