Use Cases and Deployment Scope
We are using SingleStore to power our whole app database layer.
We use it both for our basic tables and also for the analytical ones.
The magic is that we don't need to have multiple types of databases, it's just a single database which is a drop-in replacement for MySQL and it works almost exactly the same at the API level with some differences, which we can live with but hope they can improve upon (like column adjustments on the fly, foreign keys, etc.)
