CI/CD Pipeline Documentation

This document describes the comprehensive CI/CD pipeline for the OZON Seller API SDK, designed to validate all 32 API categories and ensure production readiness.

🎯 Pipeline Overview

The CI/CD pipeline consists of multiple workflows designed to ensure the highest quality standards for the complete OZON Seller API SDK:

• Primary CI/CD Validation - Comprehensive validation on every push/PR

• Manual workflow dispatch with test type selection

Monitoring Areas:

Client Performance

• Initialization time benchmarks (target: <10ms average)
• API access performance (target: <0.1ms per access)
• 95th percentile performance tracking

Memory Analysis

• Memory usage per client instance (target: <50KB)
• Memory scaling with multiple clients
• Garbage collection impact measurement

Bundle Size Analysis

• Total build size monitoring (target: <2MB)
