// Predis can prefix keys found in commands arguments before sending commands to
// Redis, even for complex commands such as SORT, ZUNIONSTORE and ZINTERSTORE.
// Prefixing keys can be useful to create user-level namespaces for you keyspace
// thus reducing the need for separate logical databases in certain scenarios.
