[Zope3-Users] Using twisted spread client within zope

[David Pratt]

Hi Stephane. It is possible to use a spread client in zope. That said, I 
am not sure whether you are attempting to integrate the new pb 
(unstable) or currently stable pb. Either way, I cannot provide code for 
you but say that this is not trivial. It also requires conforming zope 
storages to interact with. Your methods need to interact with the zope's 
storages if you want zope to do its thing properly.

This adds significantly to the complexity since the storage internals of 
zope take some time to learn and significant time to understand well 
enough to modify and construct storages. Once you have tested a suitable 
client server, you will also need to modify zope's startup to include 
your client service as part of zope's multiservice.

My advice to you is that you may be better off with a web service since 
this can be configured easily in zope since you are not involving the 
storage layer directly. It is just part of you app.

Regards,
David
