Meteor.setInterval on server side, Performance? -

i looking way clean of database entries might not need after 24hours or that, looking meteor code: https://github.com/meteor/meteor/blob/832e6fe44f3635cae060415d6150c0105f2bf0f6/packages/oauth/pending_credentials.js

i found part:

// periodically clear old entries never retrieved var _cleanstaleresults = function() {   // remove credentials older 1 minute   var timecutoff = new date();   timecutoff.setminutes(timecutoff.getminutes() - 1);   oauth._pendingcredentials.remove({ createdat: { $lt: timecutoff } }); }; var _cleanuphandle = meteor.setinterval(_cleanstaleresults, 60 * 1000); 

i couldn't find exectuion of function. wondering if var _cleanuphandle means execute every 60 seconds? , if it's seems strange endless function run every 60 seconds? might general javascript question trying understand performance of kind of thing , if can safely re use technique? main goal store temporary data on server , remove after it's not needed.

i recommend using task queue library such https://atmospherejs.com/percolate/synced-cron.

for approach, specify task , start it. can end task whenever want. note server-side.

adding task

syncedcron.add({   name: 'crunch important numbers marketing department',   schedule: function(parser) {     // parser later.parse object. note specify frequency     return parser.text('every 2 hours');   },   job: function() {     var numberscrunched = crushsomenumbers();     return numberscrunched;   } }); 

starting tasks

syncedcron.start(); 

stopping tasks

syncedcron.stop() 

there lot more options recommend checking out documentation.
