Provides a convenient way to define namespaces for different categories of data. The namespace is specified by a prefix tuple which is prepended to all tuples packed by the subspace. When unpacking a key with the subspace, the prefix tuple will be removed from the result. As a best practice, API clients should use at least one subspace for application data.

See general subspace documentation for information about how subspaces work and interact with other parts of the built-in keyspace management features.
