Become familiar with the art of object reuse by reading this article and learn the pros and cons of different reuse strategies in a multi-threaded Java application. This allows you to write more performant code with less latency. While the use of objects in object-oriented languages such as Java provides an excellent way of abstracting…

Queues are often fundamental components in software design patterns. But, what if there are millions of messages received every second and multi-process consumers need to be able to read the complete ledger of all messages? Java can only hold so much information before the heap becomes a limiting factor with high-impacting garbage collections as a…

Java serialization is a popular mechanism where you are able to serialize and deserialize complex object graphs; for example where object A can contain a reference to object B, which in turn has a reference back to object A. The problem is that this rich functionality comes at a performance cost. However, if you do…

In low-latency applications, the creation of unnecessary objects is often avoided by reusing mutable objects to reduce memory pressure and thus the load on the garbage collector. This makes the application run much more deterministically and with much less jitter. However, care must be taken as to how these reused objects are used or else…

I wrote an article on low latency microservices almost five years ago now. Chronicle Software has worked with a number of tier one investment banks to implement and support those systems. What has changed in that time and what lessons have we learnt? Read this article and learn what we learned after five years of developing…

During most of my development career, the usual code organization pattern was monolithic repository or Monorepo. There is a single large version control repository, to which all developers on the project push their commits, sometimes breaking it. Every once in a while, this goliath is released as a set of artifacts. Before this may happen,…
