meteor.js如何更新模板数据？

Question

Imagine, I have this collection post.js :

{
  text: 'Some long text, article',
  likesCount: 10
}

And template file post.html:

<template name='post'>
  Article - {{text}}
  The number of likes - {{likesCount}}
</template>

Whenever any user likes post, the data is reactively updated. Does text is also transferred from database to client on every likesCount update or only likesCount is transferred? This will cause high internet traffic where internet connection cost is high.

As I understand it, Meteor only transfers the fields that change. You can confirm this for yourself with the Network tab in Developer Tools.
