and I could pass in the "owner" parameter to the filter. The "createdById" is populated from the mobile when the object gets created and with this condition, you would only be able to pull the documents that a user created. > My immediate idea would be to just have the server code update the > document, perhaps adding an “error” property describing the problem.

All mobile clients are pulling in from the gateway and this is what will happen even if there is an "error". I was planning on changing the type of the document to "error" and PUT-ting it back to the gateway, but that would mean that all the clients will fetch it. > > Since we have 3000 mobile users and are expecting a surge in the upcoming > release (that uses SG + couchbase mobile), would it be okay to create a > channel for each user?
