Re: 回复: How many concurrent connection knox supports

[Rajesh Chandramohan <ra...@yahoo.com>]

Hi ,
 as per the Code here org/eclipse/jetty/jetty-util/8.1.14.v20131031/jetty-util-8.1.14.v20131031-sources.jar!/org/eclipse/jetty/util/thread/QueuedThreadPool.javaThe Min thread is 8 But Max is 254, So that means we can do 254 HDFS get/put concurrently right ?
private String _name;
private int _maxIdleTimeMs=60000;
private int _maxThreads=254;
private int _minThreads=8;
private int _maxQueued=-1;
private int _priority=Thread.NORM_PRIORITY;
private boolean _daemon=false;
private int _maxStopTime=100; An here the no. of acceptor is mentioned as 1  , so only one thread of incoming connection?  Could somebody explain me how the concurrent connections and sessions are managed here. I am Using knox-0.6/jetty-server-8.1.14.v20131031-sources.jar!/org/eclipse/jetty/server/AbstractConnector.java
public abstract class AbstractConnector extends AggregateLifeCycle implements HttpBuffers, Connector, Dumpable
{
    private static final Logger LOG = Log.getLogger(AbstractConnector.class);

    private String _name;

    private Server _server;
    private ThreadPool _threadPool;
    private String _host;
    private int _port = 0;
    private String _integralScheme = HttpSchemes.HTTPS;
    private int _integralPort = 0;
    private String _confidentialScheme = HttpSchemes.HTTPS;
    private int _confidentialPort = 0;
    private int _acceptQueueSize = 0;
    private int _acceptors = 1;
    private int _acceptorPriorityOffset = 0;Thanks\Rajesh

 That depends on version.0.6 and before can support no more that 8. 0.7 and later support defaultly 254.

Hi Rajesh -
Sorry for the delayed response.Please see the gateway.threadpool.max configuration parameter in [1].
The Jetty QueuedThreadPool creates the number of threads indicated in that parameter upon startup.Required connections beyond that number - default 254 - will be queued.
Hope that is helpful.

 Hi ,
 We like to know or test Knox proxy no. of concurrent connection available and how we can tune that.  It must be managed by  jetty threads and default is 254 as per the code. Can anybody elaborate how does it manage the connections . 
How exactly we should be doing load testing for knox. \Rajesh
