Subject [jira] [Commented] (CASSANDRA-10140) Enable GC logging by default
Date Thu, 20 Aug 2015 17:03:46 GMT


Ariel Weisberg commented on CASSANDRA-10140:

Does anyone remember if GC logging writes directly to disk and impacts time spent in safe
points? I can't remember if that is an issue or not.

I plumbed this code a couple of times, and come to a different conclusion every time.

> Overhead for the gc logging is very small (with cycling logs in 7+) and it provides a
ton of useful information. This will open up more for C* diagnostic tools to provide feedback
as well without requiring restarts.
