Explore how tri‑color marking powers low‑pause concurrent collectors, see concrete architecture diagrams, and learn production‑grade heap management tricks.
A deep dive into the tri‑color marking algorithm, mutator barriers, and proven patterns that power concurrent GC in modern runtimes.
Modern GCs favor short-lived objects, reclaiming them within milliseconds. This post explains the underlying algorithms, runtime optimizations, and practical coding tips.
Reader‑writer locks promise high concurrency for reads but can silently starve writers. This post explains why, how to spot it, and practical fixes.

That’s where Kafka Streams steps in: a lightweight, client‑side library that lets you write stateful stream processing applications in Java (or Kotlin) without managing a separate processing cluster. ...
