EON mode - is it quorum based?
On AWS I would like to use S3 for storage, reading thru the doc - EON mode will support that. However EON mode doc talks about a cluster and recommends a minimum of 3 nodes. Is that a recommendation or a requirement? Can I just have a 1 node EON deployment pointing to S3 for storage?
Why? : well for one this is a 'test' database and has a LOT of data and given EBS pricing things add up quickly!
