In the previous post about transducers, I did not discuss early termination of reducing functions and transducers. For the examples given in that post, early termination was irrelevant. It is, however, an important and tricky aspect of reducing functions and transducers.
Vert.x is a toolkit for developing reactive applications on the JVM. I wrote a short introductory post about it earlier, when I used it for a commercial project. I had to revisit a Vert.x-based hobby project a few weeks ago, and I learned that there were some gaps in my knowledge about how Vert.x handles failures and errors. To fill those gaps, I did some experiments, wrote a few tests, and then wrote this blog post.
Transducers are to Clojure what monads are to Haskell: an almost endless source of inspiration for blog posts and discussions. I've heard and read about transducer in the past, but never got around to taking a real close look for myself. Now that I did take a closer look, I also learned some interesting things about Java's volatile keyword, the Java memory model, and the Java Concurrency Stress tests.
