Looking at the docmentation at: http://docs.couchdb.org/en/2.0.0/replication/protocol.html#upload-batch-of-changed-documents
It says: "These Documents MUST contain the _revisions field that holds a list of the ***full*** Revision history to let Target create Leaf Revisions that correctly preserve ancestry”. i.e. the full revision history must be provided. I’m unsure why and whether you can get away with only providing the current rev and it’s parent in the history…?
