Alfresco itself already has such queues for various purposes. It's a valid and proven approach. Hybrid sync uses it as does the big data server.

There can be some strange behaviour around office saves that will cause problems for example office may move files around or delete and recreate a file when you expect and want to see a clean update. You can work through the events but it can be problematic.

And normally you would put the logic for your "custom application" within alfresco itself. Perhaps being orchestrated by workflow? But as ever it depends upon your requirements.

Hi,

Thanks for replying…Are these queues implemented through the Publishing mechanism? http://docs.alfresco.com/4.2/references/RESTful-Publishing.html

Yes, we've had a few dances with the MS Word save Shuffle…such as half saves leaving a doc named .TMP. Most critical issue was, at one point MS Word saves over CIFs were sporadically deleting the working copy…caused us serious issues, hasn't happened since Nov 29th 2013! We still run a script every 20 minutes as a result to try detect when the problem occurs so we can be proactive about restoring the working copy for users.
For others: we found this wiki page useful for understanding the shuffle pattern: http://wiki.alfresco.com/wiki/File_Server_Rename_Patterns

Thanks,
Patrick
