Sail is an open-source Apache Spark replacement written in Rust. It drops the JVM, speaks Spark Connect, and runs 4 to 6 times faster than Spark with native accelerators on ClickBench. A deep dive into its architecture, benchmarks, and production readiness.
Spark sets executor CPU requests equal to limits, so a Kubernetes cluster reserves twice the CPU it uses and refuses to schedule pending pods. Kubernetes has no native overcommit. Here is the mutating-webhook operator I use to fix it.
Introduction Benchmarking remains a critical (and often underestimated) tool when designing or validating large-scale data platforms. While many teams rely on synthetic workloads or production replays, standardized benchmarks still play a key role when comparing architectures, tuning clusters, or validating infrastructure choices. TPCx-HS is one of those benchmarks: designed to Read more
