Other notable libraries

So far, we have covered JMH, Netty, and Jackson and posited that they are core libraries focused on high performance in Java. Each is designed for a specific type of task. There are other libraries available that are worth learning about. This section explores three additional libraries: Agrona, Eclipse Collections, and Guava.

Agrona

Agrona is a data structure collection specifically designed for creating high-performance Java applications. These data structures include maps and ring buffers. An example use case is a stock trading application whose success hinges on low latency.

Key features of Agrona include the following:

• Non-blocking data structures – this supports high throughput and results in low latency
• Specifically designed for high-frequency stock and securities trading systems
• Uses direct buffers, contributing to off-heap memory management efficiencies

Let’s look at an implementation example of Agrona that...
