It seems Prodigy supports the custom loader, is there a way to use a database server as source by creating a generator? Is there a recipe available to use?

Thank you!

Hi @dna , welcome to Prodigy!

We don't have a tutorial / recipe specifically for your use-case (each one tends to be different so it's difficult to cover everything).

For what it's worth, you can check how it's done in [this example that uses an API backend](https://prodi.gy/docs/custom-recipes#example-blocks). If you look at the `recipe.py` example, the most important thing is that you define a function (in this case, `get_stream`) that takes in the examples you want and yields them with respect to the format of your [annotation interface](https://prodi.gy/docs/api-interfaces).
