<script type="text/x-red" data-help-name="mongodb out">
    <p>A simple MongoDB output node. Stores the <b>msg</b> object in a chosen collection.</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>
    <p>Currently we do not limit or cap the collection size at all... this may well change.</p>
    <p>You can also choose to <b>remove</b> items. To do so the <b>msg.payload</b> <i>MUST</i> contain an object that will select the items(s) to remove.
    A blank object will delete <i>all of the objects</i> in the collection. You have been warned...</p>
