title: MongoDB - how can i set a documents limit to my capped collection?
body: <p>I'm fairly new to <code>MongoDB</code>. I need my <code>Python</code> script to query new entries from my <code>Database</code> in real time, but the only way to do this seems to be replica sets, but my <code>Database</code> is not a replica set, or with a <code>Tailable</code> cursor, which is only for capped collections.</p>
  
  <p>From what i understood, a capped collection has a limit, but since i don't know how big my <code>Database</code> is gonna be and for when i'm gonna need to send data there, i am thinking of putting the limit to <code>3-4 million</code> documents. Would this be possible?.</p>
  
  <p>How can i do that?.</p>
