Hey Svilen, Some things: Changes only returns the "last known good" change (~handwavey~) if that makes sense - e.g. if doc a -> a' -> a'' -> a''' are processed in between you checking changes, you will not receive a', a'' at all. Document deletion inside couch is simply taking doc._id,_rev only and storing a new doc._id, doc._deleted, and _rev + 1. There is nothing stopping you re-implementing DELETE yourself (e.g. update handler server side, or client side as you like), and storing doc._id _rev AND _type as well. Alternatively, use a byte of the id to store the type if you can achieve that. That should see you right. A+ Dave
