org.apache.blur.thrift.server.TThreadedSelectorServer

A Half-Sync/Half-Async server with a separate pool of threads to handle non-blocking I/O. Accepts are handled on a single thread, and a configurable number of nonblocking selector threads manage reading and writing of client connections. A synchronous worker thread pool handles processing of requests. Performs better than TNonblockingServer/THsHaServer in multi-core environments when the the bottleneck is CPU on the single selector thread handling I/O. In addition, because the accept handling is decoupled from reads/writes and invocation, the server has better ability to handle back- pressure from new connections (e.g. stop accepting when busy). Like TNonblockingServer, it relies on the use of TFramedTransport.

    TThreadedSelectorServer.Args args = new TThreadedSelectorServer.Args(serverTransport);
    args.processor(processor);
    args.executorService(_executorService);
    args.transportFactory(new TFramedTransport.Factory());
    args.protocolFactory(new TBinaryProtocol.Factory(true, true));
    _server = new TThreadedSelectorServer(args);
    _server.setServerEventHandler(_eventHandler);
    LOG.info("Starting server [{0}]", _nodeName);
    _server.serve();
  }

    args.selectorThreads = _selectorThreads;
    args.maxReadBufferBytes = _maxReadBufferBytes;
    args.acceptQueueSizePerThread(_acceptQueueSizePerThread);
    args.acceptPolicy(AcceptPolicy.FAIR_ACCEPT);


    _server = new TThreadedSelectorServer(args);
    _server.setServerEventHandler(_eventHandler);
    LOG.info("Starting server [{0}]", _nodeName);
    _server.serve();
  }
