Kryo

Kryo is a fast and efficient serialization library for Java and Scala programming languages. Serialization is the process of converting complex objects into a format that can be easily stored or transmitted, then reconstructed later. Kryo speeds up this process by using compact binary representations, reducing the size of data and improving performance. It is commonly used in big data systems like Apache Spark to handle large-scale data processing efficiently. Overall, Kryo helps developers serialize and deserialize data quickly, making data transfer and storage more efficient in high-performance applications.
