Matt Sicker commented on LOG4J2-1733:
-------------------------------------

Yeah, StatusLogger could be sufficient here depending on how serious those exceptions are.
I'll go make a new ticket for an async appender API.

> The KafkaLog4jAppender (shipped with Kafka and usable with log4j), has a syncsend property
that improves performance significantly by not blocking a send to Kafka. I've tried many other
configuration settings and setups, but find that none of these approaches improved the logging
performance to Kafka as significantly as setting the syncsend property to false.
> Unfortunately, the syncsend property is not supported by the KafkaAppender shipped with
log4j2 and the KafkaLog4jAppender only supports log4j, so I am stuck with forking the code
and making the change myself.
> Could you please introduce this property in the KafkaAppender in log4j2?
