title: Firebase Scalability
body: <p>I'd like to develop an iOS App where you're able to find nearby people and chat with them. However, I don't know how firebase handles a lot of data. </p>
  
  <p>Example: 
  So, IF the App has 100k users. And a lot of them are always chatting, searching for nearby people, could firebase actually handle that amount of requests and posts? If not, how do you use firebase then? Does that depend on the structure I build? I appreciate each answer that can help me to decide whether to use it or not :)</p>
  
  <p>thanks</p>
