Almost. It'll update document A to a revision with no properties except for "_removed":true. > at the same time, I have another question about sync.

I'm not quite sure I understand the question. If the sync function evaluating document A calls access( ) to grant user B access to a channel, and then the next time document A is updated the sync function doesn't grant user B access, then user B will no longer have access to the channel. (Unless there is another document that still gives her access, or her account's admin_channels gives her access, or she has a role that has access.) Basically, every document in SG has metadata containing a list of user-to-channel grants. That list is rebuild from scratch every time the sync function runs. A user's access is computed by merging together the grants from all current documents. —Jens -- You received this message because you are subscribed to the Google Groups "Couchbase Mobile" group.
