It's a new feature in a version thats just in alpha so how they will look
may change in the end. There will hopefully be documentation around 4.0 GA
release.

The feature at a high level though is an interface to handle queries with
an implementing class instead of the storage engine. A usecase that the
virtual tables currently created in system_views keyspace are for exploring
whats happening on system with cqlsh or directed cql queries (instead of
nodetool with jmx).
