Subject [jira] Commented: (GERONIMO-3616) AsyncHttpClient should support a batch invocation method
Date Thu, 06 Dec 2007 19:16:43 GMT


Sangjin Lee commented on GERONIMO-3616:

I have a patch ready that addresses this issue and also GERONIMO-3617.

Essentially the sendRequest() method is modified to return a ResponseFuture instead of void.
 In addition, an overloaded version of sendRequest() is created to take an additional argument
of BlockingQueue<ResponseFuture>.  The queue will serve as a completion queue on which
a ResponseFuture object will be added as the request is complete.

The semantics is entirely analogous to a familiar java.util.concurrent.CompletionService,
although I thought creating a concrete CompletionService implementation was an overkill.

I have also created a test class that exercises the new method.

I'll be uploading the patch...

> It is desirable to have a method on AsyncHttpClient that submits multiple URLs at once.
 For example,
> public void sendRequests(HttpRequestMessage[] requests);
> One would expect it to initiate all HTTP requests as soon as possible in a non-blocking
manner and return.
> Furthermore, it would be even more powerful if it returned a list of futures or a completion
queue of results.  One idea would be to return something like a completion queue (blocking)
so that results or futures are added as they are completed.  In other words,
> public BlockingQueue<HttpResponseMessage> sendRequests(HttpRequestMessage[] requests);
