Why Do I Need This Library?

[bestickley]

Hi, maybe this is a silly question, but why do I need this library? I see on the Configuring Caching Next.js docs they have a relatively simple example of creating a cache handler using a Map. I understand you cannot use this in a distributed environment, but it seems simple enough to refactor the code to use S3 (the cache I will be using). What does this library do for me? Could you help me understand? Thank you!

I've tried reading the Introduction but it's still not clear to me.
