gbensa opened a new issue #5828: Netty UDP connector doesn't work URL: https://github.com/apache/pulsar/issues/5828 NettyServerHandler doesn't work for UDP as it will receive DatagramPacket instead of byte[] I managed to make the UDP connector working using a new NettyUDPServerHandler : public class NettyUDPServerHandler extends SimpleChannelInboundHandler<DatagramPacket> { private static final Logger logger = LoggerFactory.getLogger(NettyUDPServerHandler.class); private NettySource nettySource; public NettyUDPServerHandler(NettySource nettySource) { this.nettySource = nettySource; } @Override protected void channelRead0(ChannelHandlerContext channelHandlerContext, DatagramPacket packet) throws Exception { ByteBuf buf = packet.content(); byte[] bytes = new byte[buf.readableBytes()]; buf.readBytes(bytes); buf.retain(); nettySource.consume(new NettyRecord(Optional.ofNullable(""), bytes)); } @Override public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) { logger.error("Error when processing incoming data", cause); ctx.close(); } @Data static private class NettyRecord implements Record<byte[]>, Serializable { private final Optional<String> key; private final byte[] value; } }
