com.netflix.eventbus.spi.CatchAllSubscriber

A special subscriber that receives all events published to {@link EventBus}. This is always registered with eventbus but is disabled. In order to enable this subscriber call {@link com.netflix.eventbus.spi.EventBus#enableCatchAllSubscriber(java.util.concurrent.BlockingQueue)}with the sink (receiver) for all events.
This subscriber will only call {@link java.util.concurrent.BlockingQueue#offer(Object)} on this sink to avoid any sortof blocking. Any events for which the offer call fails are rejected.
As any other {@link EventBus} subscriber, this subscriber is async i.e. any events received by this subscriber arepushed by the eventbus in async mode. The queue size for this is {@link CatchAllSubscriber#SUBSCRIBER_QUEUE_SIZE} andthere is no batching done for events to reduce memory overheads. @author Nitesh Kant (nkant@netflix.com)
