Range-based Sharding refers to creating shards that each cover a particular range of keyspace IDs. Using this technique means you can split a a given shard by replacing it with two or more new shards that combine to cover the original range of keyspace IDs, without having to move any records in other shards. The keyspace ID itself is computed
