title: Does Firebase Firestore REST API support streaming
body: <p>I want to open a connection with Firestore REST API and push or receive events on data changes.</p>
  <p>This can be done using the EventSource / Server-Sent Events protocol.</p>
  <p>I found the documentation for Firebase Realtime database REST API  here <a href="https://firebase.google.com/docs/database/rest/retrieve-data#section-rest-streaming" rel="nofollow noreferrer">https://firebase.google.com/docs/database/rest/retrieve-data#section-rest-streaming</a> and here <a href="https://firebase.google.com/docs/reference/rest/database" rel="nofollow noreferrer">https://firebase.google.com/docs/reference/rest/database</a></p>
  <p>But I could'nt find the documentation for Firestore REST API and if it is even possible to stream from it.</p>
  <p>I tried sending get request with postman and adding the Accept header to text/event-stream but it just returns a normal response and when I change the data in my firestore database postman doesn't receive anything.
  This is the format of the URL I'm requesting:
  <a href="https://firestore.googleapis.com/v1/projects/PROJECT_ID/databases/(default)/documents/MY_DOCUMENT?key=MY_KEY" rel="nofollow noreferrer">https://firestore.googleapis.com/v1/projects/PROJECT_ID/databases/(default)/documents/MY_DOCUMENT?key=MY_KEY</a>
  <a href="https://i.stack.imgur.com/TBSAN.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TBSAN.jpg" alt="postman" /></a></p>
  <p><strong>Note:</strong> I'm already able to communicate with the rest api, my question is about the streaming capability of the api using EventSource / Server-Sent Events protocol, like this one for firebase realtime databse firebase.googleblog.com/2014/03/… but I want to know if it is available for firestore</p>
