问题 Is there a way to get the row numbers (rank) for a filtered set and append the row number to the result?

My Object: { "value1": thing, "value2": thing, "value3": thing, "roles": { "1": { "name": "Dave", "id": "1" }, "2": { "name": "Jeff", "id": "2" }, "3": { "name": "Rick", "id": "3" }, "4": { "name": "Red", "id": "4" } } }` I've tried a number of rethink queries, but none have worked thus

问题 I have 3 different pool of clients in 3 different geographical locations. I need configure Rethinkdb with 3 different clusters and replicate data between the (insert, update and deletes).
