Process Versioning

[Matthieu Riou <ma...@gmail.com>]

Hi,

I've just made a small documentation to explain how process versioning
works. For a sneak peek before it gets mirrored:

http://cwiki.apache.org/ODExSITE/process-versioning.html

Feel free to tell me if some parts aren't as clear as I thought.

Cheers,
Matthieu

Jim,

You're correct. However you need to add the endpoint definition to your
example.

If process C-1 uses endpoint foo and C-2 uses endpoint foo as well, then C-2
must be retired anyway and A can't continue using C-2. Otherwise your two
endpoints would conflict and the result is a mess. You can't enable two
processes (even two versions of the same process definition) on a single
endpoint.

On the other end if you changed C to use a different endpoint and you still
want to keep C-1 around you can still do it by "branching" which would be
renaming C to D for example and you would have C-1 and D-2 (remember that
the version number is increased globally, subversion style). That would be
an endpoint change so you'd have to update B to make it use the new endpoint
for D.

Cheers,
Matthieu

Alex,

Does that mean that if I have two proceses A and B that depend on 
process C, then they will both automatically bind to the latest version 
of process C...that is you can't nominate for process A to continue 
using Process C-1 and process B to use Process C-2.

It should bind to the newest version (ProcessC -2) based on the fact that
ProcessC-1 will be retired as a result of deploying the new version.  This
is assuming you didn't change the service name or endpoint.

Matthieu,

Solid start on the versioning document. How does versioning work in the 
case where one process interacts with another process, which is in a 
separate bundle.

This is the use case

I have BundleA-1/ProcessA-1, which calls BundleB-1/ProcessC-1. If I 
upgrade BundleB with BundleB-2/ProcessC-2 do i need to make changes to 
BundleA-1/ProcessA-1 or will it bind to the latest version of the 
ProcessC automatically?

cheers
