Feature request: filter by Relay nodeId
Right now filtering on primary and foreign keys work with the actual values from the database. This leaks an implementation detail and might be cumbersome to deal with if the datatype of this identifier changes in the future (for example from integer to uuid). If primary and foreign keys could be filtered by nodeId, this problem would be solved. Furthermore it would provide consistency with other methods that accept nodeId's.
Could you expand on how you would want to filter on nodeId? Anything beyond equalTo/notEqualTo/in/notIn? I'm thinking anything outside of those wouldn't make sense for what's supposed to be an opaque identifier.
That makes perfect sense to me, equal and in operations (and their not versions) should suffice.
