An Mnesia backed Ash Datalayer.

In your application initialization, you will need to call Mnesia.create_schema([node()]).

Additionally, you will want to create your mnesia tables there.

This data layer is unoptimized, fetching all records from a table and filtering them in memory. For that reason, it is not recommended to use it with large amounts of data. It can be great for prototyping or light usage, though.
