Why Your Service Mesh Is Slower Than You Think
The hidden cost of sidecar proxy interception. Understanding connection pool failures, TLS handshake overheads, and measuring the real latency and CPU tax of Envoy's filter chain under load.
The Backpressure Problem No One Talks About
How reactive streams backpressure signals propagate through system boundaries, where they silently fail, and what actually happens to your Kafka lag when a consumer falls behind.
Kubernetes StatefulSet Gotchas in Production
Rolling upgrades on StatefulSets behave very differently from Deployments. Unpacking local PV node locks, PVC lifecycle quirks, and the race conditions that bite you during node drains.
Raft Is Not Magic: What the Paper Does Not Explain
Reading the Raft paper gives you the algorithm. Running it in production teaches you about leader lease expiry, partition storms, snapshot transfer interruptions, and follower log divergence.
GC Tuning Is Not About the GC
Most JVM GC problems are allocation problems in disguise. A structured playbook on profiling allocation rates with JFR and async-profiler, and fixing the code before touching G1/ZGC flags.
The Real Cost of Exactly-Once in Kafka
Kafka transactions guarantee exactly-once delivery, but at a price. Unpacking epoch management, producer fencing, read isolation levels, and write latency implications of transactional producers.
