Populate integration with cache

Correct me if I am wrong but I understood mongoose'e implementation for populate as a a direct db query everytime.

It would be super nice for mongoose to support caching for objects that are populated as a configurable option (let user incorporate their own caching implementation), because currently what I would do is get the object and manually populate any reference from the cache first (then hit db if not in cache). I am not so comfortable with using the populate feature, although it is super convenient, because the extra read it incurs each time.

tldr: Does mongoose currently have caching layer support for populate feature? Or any suggestions?

No files or tests are named. Start by tracing Mongoose's populate implementation and existing documentation to determine whether populate performs a database query each time and whether a user-provided cache extension point exists. Done requires a settled scope for configurable caching, with the supported behavior documented and verified by tests.
