Hi Gray, The Java producer will block on send() when the buffer is full and block.on.buffer.full = true ( http://kafka.apache.org/documentation.html#newproducerconfigs). If you set the config to false the send() call will throw a BufferExhaustedException which, in your case, can be caught and ignore and allow the message to drop on the floor.
