I think the reason why most of your queries aren't being answered is
because you're asking questions that most people don't have the answer to.
On the automatic disconnect, anyone using Cassandra in prod doesn't really
need to think about it because we're always running queries, perhaps
millions a second.  Queries are multiplexed over a single connection.
Almost nobody ever actually runs into a case of leaving a socket open for
hours without a query, so to find out if it actually happens, someone would
have to look it up in the source.

Your questions about auditing are geared more towards if you're using a
database that's built for multi user access.  Cassandra was built to solve
a very different problem.  In most cases, you don't have hundreds of people
connecting from a shell, leaving connections open, casually querying for BI
reports.  This isn't how *most* people use Cassandra, it wasn't really
built for that.  There's better support for users & roles nowadays but it's
relatively new and that's about all you have right now.

I realize you're new to the community, and it can be frustrating to not get
answers to questions that seem completely basic and obvious, but you're
asking about areas that *most* people on this list don't have knowledge
about and zero motivation to learn, because it's not necessary to solve the
problems we face.
