Slightly off topic - can we use git-diff-able databases for faster syncing of clients with servers?

Or is there no practical difference?

We can return just the latest updated documents by maintaining a lastUpdated timestamp on client and server docs. But this would be at a document level. So, only the fields that have changed would be sent to the client.

Never trust a clock.

Yeah wall clock isn't reliable. But if the server could send a global version/logical clock, then the client can say this is the latest version I've got. Which is essentially what tcp, git, etc do.
