On demand Publish on Meteor? -

-

is there way publish updates collection on demand? (e.g. send updates every 5 seconds?)

i publishing leaderboard, shows the top 50 players (have points) in game. updates users' points happen frequently, leaderboard changes (every 1-5 seconds). every minute or so, server updates points ~100 user in foreach loop. problem publish methods start updating right away, before 100 elements have been updated. creates painful performance issue (publishing updates users multiple times)...

is there way hold publish until updates done? or way update published data every 5 seconds instead of immediately?

thanks help! :)

create custom publication , take control!

var pubshandlers = [];  meteor.publish('totalscore', function() {   this.added('someclientcollection', 'totalscoreid', {     totalscore : somegettotalscorefunction()   });   pubshandlers.push(this); //maaaaybe not cleanest thing do.   this.ready(); });  meteor.setinterval(function updatescores() {   var newtotalscore = somegettotalscorefunction()   pubshandlers.foreach(function(pubhandler) {     pubhandler.changed('someclientcollection', 'totalscoreid', {       totalscore : newtotalscore   }); }, 5000); //each 5 seconds, update

so here's what's happening:

  1. publishing in custom way, adding document our publication,
  2. remembering publication handler further updates,
  3. at later time (here in interval), use remembered handlers update document.

the main benefit keep server in full control of publication , updates.
main drawback use of push(this). it's not bad looks damn hideous...

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
