What will happe  to your projection with 100m streams?




Original test code:

fromAll().
    when({
        $init: function(s,e) { return {streanList:"", count:0} },
        $any : function(s,e) {
            if (!s.streanList){
                s.streanList =" ";
            }
            if (s.streanList.indexOf(e.streamId) < 0){
               s.streanList = s.streanList + e.streamId +",";
               s.count++;
            }
        }
    })
