> Rather than creating a byte[] of size Max Buffer Size in the onTrigger method, we could instead create a BlockingQueue<byte[]> as a member variable and then populate it in an @OnScheduled method, as we know then how many threads are being used (so we know how many byte arrays to make). This will result in far less garbage collection and higher throughput
