> According to the Datastax document for session "{color:#4c9aff}*As a given
> session can only be "logged" into one keyspace at a time (where the "logged"
> keyspace is the one used by queries that don't explicitly use a fully
> qualified table name), it can make sense to create one session per keyspace
> used. This is however not necessary when querying multiple keyspaces since it
> is always possible to use a single session with fully qualified table names
> in queries.*{color}"(source:
> [https://docs.datastax.com/en/drivers/java/3.0/com/datastax/driver/core/Session.html).]
>
> The session fields in Mutator<T> class should be cached and reused for a
> keyspace and host.
