Hi, I've read it in the past, but was hoping it's not accurate (I'm already using an asynchronous logger as the backend). It basically says that no - there is no way to achieve what I want with Akka Logging, because while an asynchronous backend may help, the messages still go through some sort of unbounded queue. So in the case of a fast producer (lots of logging requests) and a slow consumer (logging backend reading from this queue), you will still get an OutOfMemoryError.
OK, so I guess I'll just use those loggers directly and I'll have to populate the MDC on my own. Probably not that much work anyway. Thanks!
