/**
* A factory for Apache Cassandra {@link Session sessions}.
*
* A {@link SessionFactory} object is the preferred means of getting a connection. The {@link SessionFactory} interface
* is implemented by a {@link CqlSession} provider.
*
* A {@link SessionFactory} object can have properties that can be modified when necessary. For example, if the
* {@link CqlSession} is moved to a different server, the property for the server can be changed. The benefit is that
* because the data source's properties can be changed, any code accessing that {@link SessionFactory} does not need to
* be changed.
