| Hi,
I've just started looking at POE with a view to using it in conjunction
with a workflow application. The application works with a couple of
entities; a queue for new jobs (processed in batch-mode), user requests
(processed in transaction-mode).
New jobs change state (becoming partially processed jobs) and eventually
require user input to continue being processed.
There are two types of events I can think of:
1. the 'new jobs' queue requires attention.
2. a partially processed job requires attention (initiated by user input)
I want the workflow to be shared sensibly between the two modes, i.e. a
user request should be responded to asap. What happens if a user request
comes in during batch processing. Should the batch process be
interrupted? If so, how? Also, if the batch is interrupted how should it
be picked up again? Is it possible for a user request to be seamlessly
(i.e. minimal disruption) processed during batch processing?
Is this the kind of thing POE is good for?
At the moment I have a daemon that performs the transaction-based stuff
via a socket. I'm looking at my options with regard to incorporating
batch processing. Given what I read about POE so far, I think I can uses
its networking features. Can I use POE to share one resource (the
workflow) between the two modes?
I'm still reading the docs and working my way through the mailing list
archives but I'd appreciate any feedback that helps me answer my questions.
Hope this all makes sense.
Regards
Chris
