Why does serialization with Protobuf work faster compared to JSON?

Protobuf (Protocol Buffers) is faster than JSON for several reasons:

• Binary format: Protobuf serializes data into a compact binary format that takes up less space and is transmitted and parsed faster, whereas JSON is a text format that requires string parsing.

• Strict schema: Protobuf uses a predefined schema (proto file), which allows for efficient encoding and decoding of data without the need to analyze the structure at runtime.

• Less overhead: JSON contains field names in each message, increasing size and processing time, while Protobuf stores only numeric tags, saving space.

• Optimized libraries: Protobuf implementations are usually optimized for fast data transformation.

Example of using Protobuf in Go:

import (
    "github.com/golang/protobuf/proto"
)

// Serialization
data, err := proto.Marshal(yourMessage)

// Deserialization
err = proto.Unmarshal(data, yourMessage)
