title: Recommendation for an in-memory database
body: <p>I would like to remove sql dependency of small chunks of data that I load on (almost) each request on a web application. Most of the data is key-value/document structured, but a relational solution is not excluded. The data is not too big so I want to keep it in memory for higher availability. </p>
  
  <p>What solution would you recommend?</p>
