Examples with NetAddress io.dingodb.net.NetAddress used on opensource projects

Example 1 with NetAddress

use of io.dingodb.net.NetAddress in project dingo by dingodb.

the class CoordinatorConnector method connectLeader.

private void connectLeader(Message message, Channel channel) {
    byte[] bytes = message.toBytes();
    if (bytes == null || bytes.length == 0) {
        closeChannel(channel);
        initChannels();
        return;
    }
    ByteBuffer buffer = ByteBuffer.wrap(bytes);
    String host = PrimitiveCodec.readString(buffer);
    Integer port = PrimitiveCodec.readVarInt(buffer);
    NetAddress leaderAddress = new NetAddress(host, port);
    try {
        Channel newLeaderChannel = netService.newChannel(leaderAddress);
        listenLeader(null, newLeaderChannel);
        newLeaderChannel.registerMessageListener((m, c) -> {
            newLeaderChannel.registerMessageListener(this::connectAll);
            c.send(GET_ALL_LOCATION.message());
        });
        newLeaderChannel.send(PING.message(Tags.RAFT_SERVICE));
        lastUpdateLeaderTime = System.currentTimeMillis();
        log.info("Connect coordinator leader success, remote: [{}]", newLeaderChannel.remoteAddress());
    } catch (Exception e) {
        log.error("Open coordinator leader channel error, address: {}", leaderAddress, e);
        refresh.set(false);
        if (!verify()) {
            refresh();
        }
    } finally {
        closeChannel(channel);
    }
}

Example 2 with NetAddress

the class CoordinatorConnector method initChannels.

private void initChannels() {
    Channel channel;
    for (NetAddress address : coordinatorAddresses) {
        try {
            channel = netService.newChannel(address);
        } catch (Exception e) {
            log.error("Open coordinator channel error, address: {}", address, e);
            continue;

        return;
    }
}

Example 3 with NetAddress

use of io.dingodb.net.NetAddress in project dingo by dingodb.

the class CoordinatorConnector method connectAll.

private void connectAll(Message message, Channel channel) {
    connected(null, channel);
    byte[] buf = message.toBytes();
    if (buf.length == 0) {
        channel.send(GET_ALL_LOCATION.message());
        return;
    }
    ByteArrayInputStream bais = new ByteArrayInputStream(buf);
    int size = PreParameters.cleanNull(PrimitiveCodec.readVarInt(bais), 0);
    IntStream.range(0, size).forEach(i -> {
        String host = PrimitiveCodec.readString(bais);
        Integer port = PrimitiveCodec.readVarInt(bais);
        NetAddress address = new NetAddress(host, port);
        coordinatorAddresses.add(address);
