The Backend Engineering Show with Hussein Nasser

In this episode I explore why you should take some time to examine the operation you are caching before doing so. And why caching is a cop-out

The infinite scroll in social media as we know it today is despised by all. But it always start as a bad idea. It originated as a result of UI change to relief the backend database from inefficient queries.

An aws engineer discovered a 50% regression in postgres throughput while testing the new Linux 7.0 kernel. The cause turns out to be massive TLB and page faults exacerbated by Postgres process-based design. In this backend engineering show episode I dive deep into how this was discovered, the root cause and the possible fixes and workarounds.
