WebRethinkDB makes use of a range sharding algorithm to provide the sharding feature. It performs sharding on the table's primary key to partition the data. RethinkDB uses the table's primary key to perform all sharding operations and it cannot use any other keys to do so. In RethinkDB, the shard key and primary key are the same.
