Class MultiEndpointPoolSample

java.lang.Object

org.glassfish.grizzly.samples.connectionpool.MultiEndpointPoolSample

All Implemented Interfaces:

ClientCallback

public class MultiEndpointPoolSample
extends Object
implements ClientCallback

The sample to demonstrate how Grizzly client-side connection pool could be used in multi-threaded application in asynchronous/non-blocking fashion. To simulate real-world usecase we initialize 2 TCP-based echo servers, listening on two different TCP ports. On the client-side we initialize MultiEndpointPool, which caches TCP Connections to the servers. To test the connection pool - we run 100000 requests simultaneously using custom ExecutorService (we randomly chose the target server for each request). After we got responses from the servers - we print out statistics: number of requests sent (expected value is 100000), number of responses missed (expected value is 0), the total number of client-side Connections been established (expected value is <= 4).
