Subject Re: Cassandra recommended server uptime?

@rahul.xavier.singh@gmail.com, @simon.fontana.oscarsson@ericsson.com,

Thank you for answers.

I've got a really heavy data model, but no GC problems.

Moreover, gclog shows very efficient GC process and hardly any GC pauses.

So, the question remains open: how general is the practice of
semi-periodical C* node restarts?

Best regards,
Vsevolod.
