FST
A high-performance, JDK-compatible Java serialization library offering significant speed improvements and additional features like JSON serialization and off-heap maps.
What is FST?
FST (fast-serialization) is a Java library that provides a high-performance alternative to the standard JDK serialization. It serializes and deserializes Java objects much faster while maintaining compatibility with existing Serializable classes, solving performance bottlenecks in data-intensive applications.
Java developers working on performance-sensitive applications, such as trading systems, distributed systems, or middleware, who need efficient object serialization without rewriting existing code.
Developers choose FST for its significant speed improvements (up to 10x faster), its near-perfect drop-in compatibility with JDK serialization, and additional features like JSON support and off-heap maps that extend its utility beyond basic serialization.
