Every breakage is an opportunity to make our systems more resilient. After leading hundreds of incident reviews, I realize that each review can be reduced down to three simple questions. In this post I’ll go over why these questions are exhaustive and what common tactics come from answering these questions.
PCI-Express Must Match The Cadence Of Compute Engines And Networks - The Next Platform
When system architects sit down to design their next platforms, they start by looking at a bunch of roadmaps from suppliers of CPUs, accelerators, memory, flash, network interface cards – and PCI-Express controllers and switches. And the switches are increasingly important in system designs that have a mix of compute and memory types and for
How to Avoid the N+1 Query Problem in GraphQL and REST APIs [with Benchmarks]
The N+1 query problem is a performance issue you might face while building APIs, regardless of whether they're GraphQL or REST APIs. In fact, this problem occurs when your application needs to return a set of data that includes related nested data – for example, a post that includes comments.
In the first of two combined BPF and filesystem sessions at the
2023 Linux Storage, Filesystem,
Memory-Management and BPF Summit, Hou Tao introduced his BPF iterators
for filesystem information. Iterators for
BPF are a relatively recent addition to the BPF landscape; they help
BPF programs step through kernel data structures in a loop-like manner, but
without running afoul of the BPF verifier, which is notoriously hard to
convince about loops.
service discovery is the process of retrieving the list of instances of a service provider for interaction between service consumers and the server provider
