Store "old" orders/trades on a separate server/db

[JonathonDunford]

We would like users to be able to view their order/trade history without bogging down the performance of the active orderbook.

One proposed suggestion would be to move completed orders to a separate db/server and remove them from the normal order book. When users need to view their trade history, they pull off of the separate DB.

The thinking here is we don't want too much data in the normal orderbook DB as that will be hit constantly. Users don't check their trade history nearly as often, so that database could be larger as it would be hit less.
