Improve /api/v2/enrollments/ performance by rhysyngsun · Pull Request #3268 · mitodl/mitxonline

rhysyngsun · 2026-02-04T20:10:04Z

What are the relevant tickets?

Part of https://github.com/mitodl/hq/issues/9559

Description (What does it do?)

This adds a couple of performance tweaks:

Moves some fetches from select_related to prefetch_related
- This reduces the number of joins we're doing here so should be a bit more performant.
- The joins I left are ones that the API either already or potentially joins on anyway due to filtering.
Prefetches the certificate instead of N+1 queries in the serializer

Note that the OpenAPI checks are failing because I made some modifications to more explicitly specify grades and readonly to prevent drf_spectacular from putting an input type for grades into the spec (no idea why it was trying to do that) and while the check doesn't see an issue with that, it's taking issue with the fact that maxLength was dropped as a result, which really never matters because it's read-only data.

How can this be tested?

Ensure you have multiple enrollments locally
You should be able to load the mitxonline and learn dashboards and they should look and function the same but the API should return faster

I started by doing a basic performance benchmark on a filtered courses API request on this branch:

I ran this a bunch of times and the results seemed to be a bit faster subjectively when I was watching the output, both in the terminal and rendering the page.

-    grade = serializers.FloatField(min_value=0.0, max_value=1.0)
+    grade = serializers.FloatField(read_only=True, min_value=0.0, max_value=1.0)



To fix the OpenAPI spec issue, we could add letter_grade to the serializer here:

letter_grade = serializers.CharField( read_only=True, max_length=6, allow_null=True )

The spec error is complaining about the max length being changed to unlimited from 6, so this fixes that.
