Revisions for Created Documents

[Michael Beam <mi...@me.com>]

Hi There,

My application is monitoring the _changes API to update its UI for updated documents. I would also like to take actions in my app for new documents, so I wanted to get the list's opinion on detecting created documents.

Is checking the revision string for the prefix "1-" is a reliable and robust method of recognizing a change as a new document?  Everything in my experience points to yes, but I may be overlooking some subtleties about how that all works.

Thanks!

Hi Mike,


This is not completely watertight, especially considering replicating over
documents. In general, all new documents are prefixed with 1- but you can
just as easily add a document and set the _rev manually to a number higher
than 1. Setting _rev to 0 won't do the trick though.

If your scenario doesn't allow for these kind of `features`, you could use
it i guess.


Cheers,
