Have you considered the async. appender <https://logging.apache.org/log4j/2.x/manual/appenders/delegating.html#AsyncAppender>? It can be configured to drop to requests if the buffer is full, i.e., Kafka is not keeping up.
IIRC the Kafka Appender and asynchronous components don't like each other. The Kafka client library uses asynchronous calls and the Kafka asynchronous thread also generates log events. This can end up in problems like #2893[1].
When it comes to the Kafka Appender, I think a big rewrite is needed. Piotr [1] https://github.com/apache/logging-log4j2/issues/2893
