mem

Documentation

Overview

package mem provides an implementation of the app.DB interface that lives entirely in the application's runtime memory. It can be saved to and loaded from JSON files for persistence.

It performs well, but it's absolutely not intended to be used on a large user base. Deployments with more than 50 to 100 users should be set up with a proper database management system.
