> The background thread runs inside of the DefaultEventHandler to consume events from the ApplicationEventQueue and produce events to the BackgroundEventQueue.
> The background thread runnable consist of a loop that tries to poll events from the ApplicationQueue, processes the event if there are any, and poll networkClient.
> In this implementation, the DefaultEventHandler spawns a thread that runs the BackgroundThreadRunnable.  The runnable, as of the current PR, does the following things:
>  # Initialize the networkClient
>  # Poll ApplicationEvent from the queue if there's any
>  # process the event
>  # poll the networkClient
> PR: https://github.com/apache/kafka/pull/12672
