Re: [Asterisk-java-users] Handling parallel requests toAgiScript.service() method

[Martin S. <ma...@be...>]

Hello Satya,

You are correct -- the AgiScript does not serialize execution to enforce
any kind of thread safety. This is the usual case for highly parallel
operations in Java -- there's always a tradeoff between synchronization
and performance. I suggest this is a good default behavior for
Asterisk-Java.

I'd advise you design parallel requests to require as little shared data
as possible, avoiding things like static members. If you *must* share
some data, use everyone's favorite parallel data structure -- the
database (or any of the thread safe collections in a static member).
You'll still probably have opportunities where you can deadlock if
you're not careful.

There's never a free lunch :)

Best of luck,

Martin

Subject: [Asterisk-java-users] Handling parallel requests
toAgiScript.service() method

Hello

I'm setting up IVR using fastagi. I have to execute some business logic 
during the IVR flow
I'm wondering how to handle parallel requests that come to service
method.
I guess at runtime a single instance of the AgiScript will serve all 
requests, please confirm

If so, I should make my business logic thread safe, but I'm afraid that 
slows down the calls.
What is advisable to handle parallel requests?
Can I use Queues, but the AgiChannel is not Serializable

Thanks for any pointers
Satya
