hello all,
I am working on a free software for accounting and rural banking in India.
We use Pylons for web application.
Now, my question is in reference to the recent threads on this mailing list regarding sqlalchemy connections. I heard that after a certain amount of connections, the library does have some problems managing them. I have looked at some emails but I would like if some one demystifies my understanding or misunderstanding. My application is based on MVC Architecture and the core logic is coded as XMLRPC based server side APIs. We create a connection for every new client which connects to the rpc server and maintain all the connections in a list. now I forsee a situation where more than 500 connections might be alive at one time in the list. I understand that sqlalchemy has some limitations on the number of connections (engines ) and their respective session objects which can be kept alive at the same time?
if this is true, can i create some kind of a connection pool for the server?
This way connections can be recycled and used for a lot of clients and new connections will only be created when needed. I want to avoide this situation, so I really want to know if there is some kind of upper limit on the number of engines that can be active at one time.

Happy hacking.
Krishnakant.
