[ZODB-Dev] Replicated ZEO

[Matt Gregory]

Well, it works like this:  Let's say you have a production Zope (or a bunch
of them), and a Development Zope.  Each Zope ZODB instance (Zope standalone
or ZEO server) to which you wish to sync must have at least one client with
a ZSyncer installed and configured.  When you are ready to publish some
resources from your development Zope to all of your production Zopes, you
issue the Sync command and it will connect to all of the produciton machines
listed and use XML-RPC to send out your chages.

Because ZSyncer is a Zope product, it's methods are exposed to Zope Python.
If you wish to have it sync on a schedule, or when stuff is added or
anything else then you can add a script to do it.  I have not searched, but
I'm almost positive that you could find one which has already been writen if
you want.

For my uses, Syncing should only happen to production when the development
version is ready to deploy.
