This document summarizes a presentation on serialization frameworks and their performance. It discusses the purpose of serialization, common data formats like binary, XML, and JSON, and several Java serialization frameworks including Java serialization, Kryo, Protocol Buffers, Jackson, Google GSON, and others. Benchmark results show that Kryo and Protocol Buffers generally have the best performance for serialization and deserialization speed as well as output size. The document provides recommendations on when to use different frameworks based on usage cases and priorities for speed, size, or flexibility.
