Most of the time, the client and server can exchange deltas to get from one | |||
version of the dataset to another. They'll only need to send a full version | |||
when the client is so out-of-date that the server no longer remembers their | |||
earlier state (and thus cannot compute or accept a delta from it), or when | |||
the client is uploading their dataset for the first time. | |||
To tolerate intermittent connections and overloaded servers, the protocol | |||
that transfers deltas should also let both sides paginate the data, sending | |||
it in smaller chunks. | |||
