I think it would be helpful if some of these posts included scale. There are almost always two groups talking past each other
- I run my B2B application, Postgres only, and it is perfect for my 50k MAU. No complaints, sleeping soundly with the low complexity and a two man team.
- I work at FAANG, where we have 1 billion DAU, and this is a joke. Would fall over immediately. The dedicated ops teams for Kubernetes, Elastic, and Redis have never complained about scaling issues.
