----------------------------------------------------------------------------
I decided to start an instance of Cassandra to see how the table looks like
now. Unfortunately, it became too wide and rows span in few rows. This will be
hard to read.
I need to think about it a bit more. I will continue on Monday.

> and
> [ApplicationVersion|https://docs.datastax.com/en/drivers/java/4.9/com/datastax/oss/driver/api/core/session/SessionBuilder.html#withApplicationVersion-java.lang.String-].
> It would be helpful to expose this information via virtual table
> {{system_views.clients}} and with {{{}nodetool clientstats{}}}.
> +Additional information for newcomers:+
> The drivers can send as part of the {{STARTUP MESSAGE}} the
> {{APPLICATION_NAME}} and {{APPLICATION_VERSION}} options. Two new volatile
> fields {{applicationName}} and {{applicationVersion}} need to be added to
> {{ClientState}} in a similar way to {{driverName}} and {{{}driverVersion{}}}.
> The {{APPLICATION_NAME}} and {{APPLICATION_VERSION}} options need to be
> retrieved in {{StartupMessage#execute}} and passed to the
> {{{}ClientState{}}}.
> The new {{application_name}} and {{application_version}} columns need to be
> added to the {{system_views.clients}} represented by the {{ClientsTable}}
> class. The data then need to be retrieved from the {{ClientState}} through
> {{{}ConnectedClient{}}}.
> Some unit tests similat to {{SettingsTableTest}} should be added.
