AsyncAppender and dynamically created appender
Is is possible to have the delegate(s) of AsyncAppender created
dynamically, just like the delegates of RoutingAppender?

Let's consider https://issues.apache.org/jira/browse/LOG4J2-1043 to be a
request for that

That seems like a reasonable approach to me. Those appenders should only stop when the background thread stops.

Re: AsyncAppender and dynamically created appender
Posted by Mikael Ståldal <mi...@magine.com>.
Would it make sense to allow AsyncAppender to have dynamically created
delegate appenders (and not only AppenderRefs)? And initialize those
delegate appenders in AsyncAppender's background thread?

Yes, this is related to an appender hanging or throwing an exception on

Is this related to an appender hanging or throwing an (unchecked) exception

Re: AsyncAppender and dynamically created appender
Posted by Ralph Goers <ra...@dslextreme.com>.
The Appenders used by the AsyncAppender are known at configuration time. So starting and stopping them in conjunction when the configuration is initialized makes sense (and makes managing them easier). The Appenders created by the RoutingAppender are dynamic - the number of them and their configuration is not completely known at configuration time. They are created based upon the events that are being processed. This makes managing them a bit harder.
Note that when FileConfigurationMonitor detects a configuration change it starts a new Thread to perform the reconfiguration, so I am not sure what you are hoping to gain by configuring Appenders asynchronously.

Re: AsyncAppender and dynamically created appender
Posted by Mikael Ståldal <mi...@magine.com>.
I want to create / initializte the delegates of an AsyncAppender
asynchronously, to protect the application from exceptions and delays in
delegate appender initialization. Is that possible with routing appender?
(See https://issues.apache.org/jira/browse/LOG4J2-1043 )

You could have a routing appender as the delegate of an async appender.
