/**
* A factory for Apache Cassandra sessions.
* <p>
* An alternative to the {@link com.datastax.driver.core.Cluster} facility, a {@link SessionFactory} object is the
* preferred means of getting a connection. The {@link SessionFactory} interface is implemented by a {@link Session}
* provider.
* <p>
* A {@link SessionFactory} object can have properties that can be modified when necessary. For example, if the
* {@link Session} 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.
