Order of document synchronization

Let’s say documents A, B, and C are quickly created and saved in that order. When Couchbase Lite syncs these documents to the server, is it guaranteed that the server see these documents arrive in the order in which they are saved?

Similarly, if documents X, Y, and Z are created and saved on device 1 in that order, would they appear on device 2 in that order?

No, the order of documents is not guaranteed.
