Replacing the database in Active Record with RPC-based interface

Hi there,

We're about to move our persistent store from a MySQL database to an RPC-based data store.

However, we really like programming against the AR-api, and would like to keep as much as possible from, so that we can keep stuff like callbacks, validations, relations etc.

How would you do it?

Does it make sense to replace the mysql-adapter with and RPC-based adapter, translating SQL statements into equivalent rpc calls? And the convert the result-set into whatever AR uses in its conversion into objects?

It's probably easiest to create your own model class from scratch that mimics the same API. I started working on porting more abstract model concepts (observers, validators, callbacks, etc) to a very experimental ActiveModel project so this job should be easier in the future. But, Rails 2.0 has taken priority.
