Java: How Object Reuse Can Reduce Latency and Improve Performance

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 away complexity, frequent object creation ...

Evolutionary Database Design is a slightly counterintuitive approach to managing a database. On the one hand, we think of our databases as towers that we must defend from any old change and must deploy to carefully.

As I have said, I find that computers are just that, a system that does mathematical computations and nothing more. While we claim that our computers are ...

Java: Why a Set Can Contain Duplicate Elements

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 unexpected results might manifest themselves, ...
