Module json_optimization 

JSON Optimization Module

This module provides comprehensive JSON optimization utilities for the Ultrafast Gateway, reducing payload sizes and improving performance through intelligent JSON compression and field optimization.

Overview

The JSON optimization system provides:

• Payload Size Reduction: Remove unnecessary fields and null values
• Field Compression: Compress field names and values
• Request Optimization: Optimize outgoing requests to providers
• Response Optimization: Minimize response payload sizes
• Size Tracking: Monitor payload size reductions
• Performance Metrics: Track optimization effectiveness

Optimization Strategies

Field Removal

Removes unnecessary fields to reduce payload size:

• Null Values: Automatically removes null fields
• Empty Arrays: Removes empty array fields
• Default Values: Removes fields with default values
• Optional Fields: Removes optional fields when not needed

Field Compression

Compresses field names and values for size reduction:

• Field Name Mapping: Maps long field names to short codes
• Value Compression: Compresses repeated values
• Numeric Optimization: Optimizes number representations
• String Compression: Compresses string values

Request-Specific Optimization

Optimizes different request types:

• Chat Completions: Optimizes chat completion requests
• Embeddings: Optimizes embedding requests
• Image Generation: Optimizes image generation requests
• Audio Processing: Optimizes audio processing requests

Usage

use ultrafast_gateway::json_optimization::JsonOptimizer;
use serde_json::Value;

// Optimize a request payload
let original_request: Value = serde_json::from_str(r#"{
    "model": "gpt-4",
    "messages": [{"role": "user", "content": "Hello"}],
    "temperature": 0.7,
    "max_tokens": 100,
    "unnecessary_field": null
}"#)?;

let optimized = JsonOptimizer::optimize_request_payload(&original_request);

// Calculate size reduction
let reduction = JsonOptimizer::get_size_reduction(&original_request, &optimized);
println!("Size reduction: {:.2}%", reduction * 100.0);

Performance Benefits

The optimization system provides significant benefits:

• Reduced Bandwidth: Smaller payloads reduce network usage
• Faster Transfers: Smaller payloads transfer faster
• Lower Costs: Reduced data transfer costs
• Better Caching: Smaller payloads cache more efficiently
• Improved Latency: Faster request/response cycles

Compression Algorithms

The system uses multiple compression techniques:

• Field Mapping: Maps common field names to short codes
• Value Deduplication: Removes duplicate values
• Structure Optimization: Optimizes JSON structure
• Type Optimization: Optimizes data type representations

Monitoring

The system tracks optimization metrics:

• Size Reduction: Percentage of size reduction achieved
• Compression Ratios: Compression effectiveness metrics
• Performance Impact: Optimization overhead tracking
• Cache Efficiency: Cache hit rate improvements
