azure service fabric - Incremental actor state replication? -

-

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.

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
