azure - DocumentDB, How to work with continuationToken in a SP -

-

the next sp suppose run on collection , keep query next batch of documents (10 docs every batch). instead return same 10 documents every time.

function sample(prefix) { var continuations = [], ids = [],  context = getcontext(),      collection = context.getcollection(),      response = context.getresponse(); var queryoptions = { pagesize: 10, continuation: null };  (i = 0; < 10; i++) {     // user wish list actions     var query = "select * w",     accept = collection.querydocuments(collection.getselflink(), query, queryoptions, processmultiusers);     if (!accept) throw "unable read user's sessions"; } getcontext().getresponse().setbody(ids);   function processmultiusers(err, docs, options) {     if (err) throw new error("error: " + err.message);     if (docs == undefined || docs.length == 0) throw new error("warning: users not exists");      (j = 0; j < docs.length; j++) {         ids.push(docs[j].userid);     }     queryoptions.continuation = options.continuation;     continuations.push(options.continuation); }}

in script wrote, execution of queries done synchronously , queued same initial continuation token, null. instead, need take token first query , queue next , continue.

the below sample should achieve looking for

function sample(continuationtoken) {     var collection = getcontext().getcollection();     var maxresult = 10;     var documentsprocessed = 0;     var ids = [];     var filterquery = "select * w";      tryquery(continuationtoken);      function tryquery(nextcontinuationtoken) {         var responseoptions = { continuation: nextcontinuationtoken, pagesize: maxresult };         if (documentsprocessed >= maxresult || !query(responseoptions)) {             setbody(nextcontinuationtoken);         }     }      function query(responseoptions) {         return (filterquery && filterquery.length) ?             collection.querydocuments(collection.getselflink(), filterquery, responseoptions, onreaddocuments) :             collection.readdocuments(collection.getselflink(), responseoptions, onreaddocuments);     }      function onreaddocuments(err, docfeed, responseoptions) {         if (err) {             throw 'error while reading document: ' + err;         }          documentsprocessed += docfeed.length;          (var = 0; < documentsprocessed; i++) {             ids.push(docfeed[i].userid);         }          if (responseoptions.continuation) {             tryquery(responseoptions.continuation);         } else {             setbody(null);         }     }      function setbody(continuationtoken) {         var body = { continuationtoken: continuationtoken, documentsprocessed: documentsprocessed, ids: ids };         getcontext().getresponse().setbody(body);     } }

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...
