i'm wondering whether actor state, in service farbic, replicated using kind of incremental delta/diff mechanism or whether full state replicated each change. let's have actor quite large state payload, 100kb. let's counter value embedded in state. counter changed on high frequency while rest of state changed on low frequency. in case, wasteful if full state replicated each change , should consider design. however, if service farbric capable of doing incremental replication approach attractive. does know details on this? perhaps service fabric use binary delta/diff algorithm on serialized state during replication, or perhaps state changes incremental per state name ? it's per state name. if @ method iactorstateprovider.savestateasync method, you'll see accepts list of actorstatechange . persisted provider ( kvsactorstateprovider ) serializes each of values in list (except in case of remove), , updates store.
