Hi Mohit, Thanks for your reply.
If my use case is purely querying read-only data (no transaction scenarios), at what scale is one of them a better option than the other? I am aware that for scale which can be supported on a single node, VoltDB is a better choice. However, when the scale grows to a clustered scenario, which is the right engine at various degrees of scale?
