Hello, I have a question regarding Prefect2.0. My team was using Prefect1.0 earlier and had been using the Graph QL functionality. Do we have this functionality in Prefect 2.0 as well?

Hi. The GraphQL API has been swapped out for a REST API

Thank you for getting back @Stéphan Taljaard! If possible can you please provide the documentation for the same?

Hi Divya, Check out these docks for an Overview of 2.0 APIs. Check out this if you are just interested in checking out the Prefect 2.0 REST API.

Thank you sharing the documentation. Will go through!

Out of curiosity, what was the motivation for abandoning GraphQL in favour of REST?

Hi @Sebastian 🙂

Our CTO Chris White did a great job of answering this question live the other day.

Here's a link to the timestamp▾

of that recording.

In summary

• Lots of people were unfamiliar with GraphQL and asking for RestAPI

• For Prefect Server specifically, because we chose to use GraphQL, that’s the reason why Prefect Server is so heavy - we needed the query schema off of the database (which is what Hasura does)

• For our business logic, we had all of our mutations defined in Python code

• Those are two separate GraphQL schemas so we had to stitch them together

• All of this resulted in a very large, heavy container that was Prefect Server

• REST is very lightweight and allows us to automatically pull in Prefect flows into the UI even if they ran before the UI was launched

• Finally, GraphQL is very hard to manage when exposing publicly to a high volume of usage

Thank you @Taylor Curran for the great insights 🙂
