Good catch on the metrics! We do use Preset for metrics and dashboards, and obviously Preset isn't going to talk to our in-memory database. So we do have a separate MySQL database where we just push analytics data. (e.g. each time an event of interest happens.) We never read from this database, and the data is a schemaless JSON. Preset then queries from this database for our metrics purposes.
