Multiple Request Processor

[Karthik D V]

Hi All,
I have the following requirement.

I have table which contains requestID, priority and the request
status(status can be 'Queued','Procesing','Completed','Failed')

I need a class which takes 5 top priority requests and process the
same simultaniously, now if any of these requests completed, for the
same slot I should get the next priority requests to process.

How do I do this? I thought og doing using ThreadPool, but in
threadPool we dont have the facility to know whether the given thread
is completed or not

Please help me in this regard.

Thank you.

Use an array of Thread objects, and monitor the ThreadState property of
them.

It seems to me that a simple approach would be to use the
BackgroundWorker class, handle the RunWorkerCompleted event, and in your
handler, start a new BackgroundWorker from your queue of prioritized
requests.

You would initialize the whole thing by starting five BackgroundWorkers
initially, and then only starting a new BackgroundWorker after that in
your RunWorkerCompleted event handler.

If you have the ability to add new requests after processing has
started, then you would want to keep a counter of the active requests
(add one when you start a BackgroundWorker, subtract one in the
RunWorkerCompleted event handler), and allow for a new requests to be
started as it's added if you are under your maximum of five.
