title: Cloud Firestore in Datastore Mode - Are sharded counters not going to be needed anymore?
body: <p>The documentation states:</p>
  
  <blockquote>
    <p>Cloud Firestore in Datastore mode Cloud Firestore in Datastore mode
    uses Cloud Datastore system behavior but accesses Cloud Firestore's
    storage layer, removing the following Cloud Datastore limitations:</p>
    
    <p>Eventual consistency, all Cloud Datastore queries become strongly
    consistent. </p>
    
    <p>Transactions are no longer limited to 25 entity groups.</p>
    
    <p>Writes to an entity group are no longer limited to 1 per second.</p>
  </blockquote>
  
  <p>My question is: Is there a new limit to how many times an entity group can be updated a second? Or is it supposedly infinite based on the above? Can't seem to find any more info.</p>
  
  <p>Ultimately, I am wondering if sharded counters would still be needed for an entity like a "page views counter" that could potentially be updated 500+ times a second at peak times.</p>
