&gt; Coming from PostgreSQL, you could do the same using LISTEN&#x2F;NOTIFY?<p>I have to admit I was not aware of this feature.<p>However, from the docs[1]:<p>&gt; Commonly, the channel name is the same as the name of some table in the database, and the notify event essentially means, &quot;I changed this table, take a look at it to see what&#x27;s new&quot;.<p>From what I understand, you just know that <i>something</i> has changed, the actual change is not included in the event, so you need at least another query to see what changed.<p>Did I understand correctly?<p>In MongoDB you get the operation (insert, update, delete), the document and another few details right in the event.<p>[1] <a href="http:&#x2F;&#x2F;www.postgresql.org&#x2F;docs&#x2F;9.4&#x2F;static&#x2F;sql-notify.html" rel="nofollow">http:&#x2F;&#x2F;www.postgresql.org&#x2F;docs&#x2F;9.4&#x2F;static&#x2F;sql-notify.html</a>
