title: Saving to firestore objects more than 1MB
body: <p>Hi I read that the limitation of the Firestore max document size is 1MiB.</p>
  
  <p>I want to store heart rate and other "activity" data and my current model is similar to this</p>
  
  <pre><code>-activity
    - HR points stream (1 point per second up to 86400 points)
    - Lat points stream (same as above)
    - Long points stream (same as above)
  </code></pre>
  
  <p>The above number (86400), for example, is for 24h of storage. </p>
  
  <p>In general, I am trying to eg store and get a let's say 24h run that someone did. </p>
  
  <p>However, due to the firestore limitations on size, this is getting to predict. </p>
  
  <p>Can you suggest or guide to the right direction of what would someone do in order to store such "big" data? </p>
  
  <p>I have tried to separate the above streams to their own documents but with no luck as a stream of heartrate even can get too much data for the firestorm to store. </p>
  
  <p>So in short what are the recommendations for storing big streams of data only with the firestore and not using for example cloud storage? </p>
