You added Redis because that is what you are supposed to do, and you genuinely don't know if the endpoint is any faster.
What you'll have at the end
A before-and-after log of hit rate and response time for the one endpoint you cached, with a clear yes-or-no on keeping it
You need
An endpoint that already reads through a cache-aside layer in front of a real, non-trivial database query, live somewhere you can point a load-testing tool at it and flip the cache path on and off.
Not covered
Deciding which query was worth caching in the first place, or choosing between a local cache and a shared one: this assumes that call is already made and only settles whether it paid off.
Leans on
Add a cache-aside layer in front of one query
if that layer doesn't exist yet, build it first: this recipe only measures a cache that's already in place.
A Redis eviction policy that silently drops the keys your app still needs
if the pool checks out clean but keys are quietly disappearing instead, that's a different diagnosis with its own fix.
