thrift-pool-client

A Thrift Client pool for Java

• raw and type safe TServiceClient pool
• Multi backend servers support
• Backend servers replace on the fly
• Backend route by hash or random
• Failover and failback support
• jdk 1.8 only

// init a thrift client
ThriftClient thriftClient = new ThriftClientImpl(() -> Arrays.asList(//
        ThriftServerInfo.of("127.0.0.1", 9090), //
        ThriftServerInfo.of("127.0.0.1", 9091) //
        // or you can return a dynamic result.
        ));
// get iface and call
System.out.println(thriftClient.iface(Client.class).echo("hello world."));

// get iface with custom hash, the same hash return the same thrift backend server
System.out.println(thriftClient.iface(Client.class, "hello world".hashCode()).echo(
        "hello world"));

// customize protocol
System.out.println(thriftClient.iface(Client.class, TBinaryProtocol::new,
        "hello world".hashCode()).echo("hello world"));

// customize pool config

// ... customize pool config here
// customize transport, while if you expect pooling the connection, you should use TFrameTransport.
Function<ThriftServerInfo, TTransport> transportProvider = info -> {
    TSocket socket = new TSocket(info.getHost(), info.getPort());
    TFramedTransport transport = new TFramedTransport(socket);
    return transport;

                ThriftServerInfo.of("127.0.0.1", 9091) //
                ), DefaultThriftConnectionPoolImpl.getInstance());

Know issues

You shouldn't reuse iface returned by client.
