How Protobuf Works
Serialization and Deserialization
Serialization converts data structures into a binary format for efficient storage or transmission. Deserialization reverses this process, converting the binary data back into usable data structures. Protobuf excels in both processes due to its compact binary format. This efficiency reduces the time and resources needed for data parsing.
Data Structure and Schema
Protobuf uses a schema to define the structure of the data. The schema specifies the data types and their relationships. Developers write the schema in a .proto file. The Protobuf compiler then generates classes based on this schema. These classes handle the serialization and deserialization processes automatically. This approach ensures that the data remains consistent and easy to manage across different systems.
