title: Best way to store answers from users in Facebook bot chat?
body: <p>Building a Facebook messenger bot using Claudia JS and plan on hosting on AWS Lambda.</p>
  
  <p>I want to ask the user a series of questions. </p>
  
  <p>When a user responds with an answer, I need to save that for later and once I have all the information I need, I will pass the answers to a function.</p>
  
  <p>What is the best way to save this information?</p>
  
  <p>I was thinking some caching layer such as redis but because that is stored in RAM I will lose it when lamda server shuts down. Mongodb apparently has a lot of overheads when connecting but will at least be persistent.</p>
  
  <p>Perhaps just a simple mySQL server?</p>
  
  <p>How does everybody else do it? I feel like there is a simple solution that I am missing.</p>
