org.apache.logging.log4j.core.async.DefaultAsyncQueueFullPolicy

org.apache.logging.log4j.core.async.DiscardingAsyncQueueFullPolicy

All Implemented Interfaces:

AsyncQueueFullPolicy

public class DiscardingAsyncQueueFullPolicy
extends DefaultAsyncQueueFullPolicy

Discarding router extends the DefaultAsyncQueueFullPolicy by first verifying if the queue is fuller than the specified threshold ratio; if this is the case, log events more specific than the specified threshold level are dropped. If this is not the case, the default routing rules hold.
