Data processing in Parallel (Hackathon project)

Dude, you have no database migration to create the table. Put one in! How can anyone help you if you haven’t took care to create the DB schema?

EDIT: I mean, it’s pretty simple, you should have included it:

defmodule Store.Migrations.AddProducts do
  use Ecto.Migration

  def change do
    create table(:products) do
      add(:name, :string)
      add(:bar_code, :string)
      add(:price, :string)
      add(:currency, :string)
      timestamps(type: :utc_datetime_usec)
    end
  end
end
