The previous chapter focused a bit on optimization in terms of splitting the query across cloned instances, which would be only part of a true database scalability concern. The database would still have performance concerns, as there is replication lag coupled with a fragile splitting mechanism through the proxy. The best route to take to reduce all of these concerns, is to architect a distributed database from the very beginning.
In the sharding write pattern, we take the previous concepts a bit further in-depth, by not analyzing the query to determine which instance to execute against.
