I've noticed that there are several Async implementations of standard
appenders out in the wild. Is there a reason none of these have made there
way into the core product? Is it just b/c no one has taken the time to do a
pull request, or is there some other reason?
I've had several projects where
Log4j core provides about 4 flavours of async logging, several of which use
non-blocking data structures.
Can you link to the ones you think should be included?
Thanks!

Like the Kafka appender's async option? Or like the async logger and
appenders?

Sorry I meant to send this to the Log4Net distro

Oh, no worries, you're on the correct list!

Ok then, so are the same Async Appenders available in Log4Net that are in
Log4j ?
Here are some one I'm using:
https://github.com/cjbhaines/Log4Net.Async
(my .net standard port: https://github.com/wjdavis5/Log4Net.Async)
Also been looking into an Async Buffering Appender. Just seems we coul

Jochen, I dont believe that appender has been ported to Log4Net. Maybe
thats what we should do first? Im sure there are other uses cases out there
though, which is why we've seen several people roll async appenders in the
first place (although it could be a fundamental lack of understanding
