In the old days of the internet, asking for anything searchable is the action of last resort, and generally considered quite rude unless truly unfindable or incomprehensible. Taking action on one's own intellectual curiosity is invaluable for education.
Although, in a lower comment, talking through how the performance benchmarks were about using Redis for persistence was really helpful to me. I don't think I would have ever had that realization had I not asked the "dumb question" at first.
My hesitation with just asking my real question on using Redis for caching was that I didn't really understand what "pipelining" is. I've misinterpreted documentation so many times that I've found it's useful to ask dumb questions, even if the only value is to get validation that you were right.
