> The current implementation of the internal memory queue has blocking semantics for the
sender. This has the potential of blocking the sender (such as log4j socket appender application)
when the queue is full. This jira provides an implementation of a non blocking queue and exposes
configuration parameters to switch the queue implementation as well as specify the max size
of the queue.
