FASTJSON2 - High-Performance Java JSON Library
FASTJSON2 is a high-performance Java JSON library designed for efficiency and speed in serialization and deserialization tasks across various Java applications.
Project Introduction
Summary
FASTJSON2 is Alibaba's next-generation high-performance JSON library for Java. It builds upon lessons learned from FASTJSON 1.x and aims to be the fastest JSON library available for Java, while maintaining a user-friendly API.
Problem Solved
Traditional JSON libraries can become performance bottlenecks in high-throughput or large-scale applications, leading to increased CPU usage and slower response times. FASTJSON2 addresses this by optimizing every aspect of the JSON processing pipeline.
Core Features
Extreme Performance
Provides industry-leading performance for JSON parsing and generation, significantly reducing overhead.
Broad Compatibility
Offers extensive compatibility with various Java data types and features, including generics, inheritance, and custom serializers/deserializers.
Ease of Use
Designed to be easy to integrate and use with minimal code changes in existing Java projects.
