<p>Update can add a object if it does not exist or update multiple objects.</p>

<p>By default MongoDB creates an <i>_id</i> property as the primary key - so repeated injections of the same <b>msg</b> will result in many database entries.</p>
|

<p>If this is NOT the desired behaviour - ie. you want repeated entries to overwrite, then you must set the <b>msg._id</b> property to be a constant by the use of a previous function node.</p>
|

<p>This could be a unique constant or you could create one based on some other msg property.</p>
