- Pagination tuning. The default page size of 20 will result in an unnecessary large number calls to the Catalog API since production currently has over 3200 courses in the CourseOverview table. Will need to determine a good approach to find the ideal value. Making the page size dynamically configurable will help with tweaking this number (will be addressed as part of ECOM-6834).
- CCX courses. It's unclear whether the Catalog service's course-marketing URL API will return the correct value for CCX courses. If it doesn't, the management command will have to explicitly get the parent course of each CCX course before sending the request to the API. Handling CCX courses can be implemented as an iterative change and need not be included as part of the initial rollout of this change, but should be handled.
- Inter-team dependencies. An early conversation and support with an edx/devOps member and ECOM is recommended to help this project go faster.
- Pagination bug (fix in progress). Currently, the LMS has not done a bulk query of the Catalog service in production. We found a pagination issue in our previous attempt at this feature, that is now being fixed by ECOM.
- Mobile enrollment API performance (orthogonal bug created). In writing this document, I noticed that the Mobile enrollment API is currently not making bulk SQL queries where it should. So the expected SLA of under 2-seconds is not being met (NewRelic link). However, this is an orthogonal issue and should be fixed separately.
