You might not even need DBConnection. Since LanceDB can speak SQL then you could maybe try shim it with Ecto.SQL.Adapters.SQL.
Or look at GitHub - Schultzer/ecto_qlc: QLC-based adapters and database migrations for Ecto · GitHub or GitHub - foundationdb-beam/ecto_foundationdb: FoundationDB Adapter for Elixir's Ecto · GitHub for none DBConnection Ecto adapters.
