Not so long ago, one of our users reached out for a case of weird hardware utilization. They were using our ILP (InfluxDB Line Protocol) client to insert rows into their QuestDB database, but along with disk writes, they also observed significant disk reads. That's definitely not expected from a write-only workload, so we had to get to the bottom of this problem. Today we share this story, full of
A few weeks ago, Kelsey Hightower wrote a tweet and held a live discussion on Twitter about whether it's a good idea or not to run a database on Kubernetes. This happened to be incredibly timely for me, since we at QuestDB are about to launch our own cloud database service (built on top of k8s)!

SIMD instructions are specific CPU instruction sets for arithmetic calculations that use synthetic parallelization. This approach allows us to perform the same calculations and operations on numerous data points simultaneously. This post describes how SIMD works with typical operation performance and describes additional optimizations we managed to achieve. What are SIMD operations? Instead of sp
