Serialization is the process of converting an object into a byte stream to store or transmit the object. The document discusses three serialization frameworks: Avro, MessagePack, and Kryo. Avro uses a JSON-defined schema and is created by the creator of Hadoop. MessagePack supports rich data structures like JSON and has interfaces for RPC. Kryo makes serialization easy by collecting serializers by class and supports compression.

3. What is Serialization?

5. Avro
• Apache Foundation
• JSON defineded Schema

6. Avro
• Created by Doug Cutting, the Creator of
Hadoop
• Data is always accompanied by a schema
- Support for dynamic typing-code
generation is not required

7. Performance of Avro
• Avro is not the fastest, But is in the top half

8. Message Pack
• Rich data structures - JSON
• Interface Definition Language(IDL) - thrift
• Create Schema Based Annotaion
• RPC
Sync,Async Support
Event-Driven I/O

Message Pack

11. Kryo
• Google Code
• Easy to Collect Serializers Case By Class
• Support Compression
• Kryo TCP & UDP client/server library
