Synchronization of client machines with a content management system repository

A system comprising computer hardware configured to provide operations of a synchronization queuing service, the operations comprising:

• receiving, at the synchronization queuing service from a client machine subscribed to a content item maintained by a content management system repository, a file synchronization request comprising an identifier of the content item;
• determining, based on the file synchronization request, whether a change to the content item in the content management system repository and/or a change to a local copy of the content item that is stored on the client machine occurred since a most recent synchronization of the local copy of the content item with the content item in the content management system repository;
• and
• responding, based on determining the change to the content item and/or the change to the local copy, to the client machine with a file event summary, the file event summary comprising:
• instructions for the client machine to directly contact the content management system repository when local copy of the content item is consistent with a current state of the content management system repository and/or when the synchronization queuing service determines the change to the content item in content management system repository.

A computer-implemented method for implementing a synchronization queuing service, the method comprising:

• receiving, at the synchronization queuing service from a client machine subscribed to a content item maintained by a content management system repository, a file synchronization request comprising an identifier of the content item;
• determining, based on the file synchronization request, whether a change to the content item in the content management system repository and/or a change to a local copy of the content item that is stored on the client machine occurred since a most recent synchronization of the local copy of the content item with the content item in the content management system repository;
• and
• responding, based on determining the change to the content item and/or the change to the local copy, to the client machine with a file event summary, the file event summary comprising:
• instructions for the client machine to directly contact the content management system repository when local copy of the content item is consistent with the current state of the content management system repository and/or when the synchronization queuing service determines the change to the content item in content management system repository.
