chrislu	5eca636c5e	mq(kafka): Add comprehensive API version validation with Metadata v1 foundation 🎯 MAJOR ARCHITECTURE ENHANCEMENT - Complete Version Validation System ✅ CORE ACHIEVEMENTS: - Comprehensive API version validation for all 13 supported APIs ✅ - Version-aware request routing with proper error responses ✅ - Graceful handling of unsupported versions (UNSUPPORTED_VERSION error) ✅ - Metadata v0 remains fully functional with kafka-go ✅ 🛠️ VERSION VALIDATION SYSTEM: - validateAPIVersion(): Maps API keys to supported version ranges - buildUnsupportedVersionResponse(): Returns proper Kafka error code 35 - Version-aware handlers: handleMetadata() routes to v0/v1 implementations - Structured version matrix for future expansion 📊 CURRENT VERSION SUPPORT: - ApiVersions: v0-v3 ✅ - Metadata: v0 (stable), v1 (implemented but has format issue) - Produce: v0-v1 ✅ - Fetch: v0-v1 ✅ - All other APIs: version ranges defined for future implementation 🔍 METADATA v1 STATUS: - Implementation complete with v1-specific fields (cluster_id, controller_id, is_internal) - Format issue identified: kafka-go rejects v1 response with 'Unknown Topic Or Partition' - Temporarily disabled until format issue resolved - TODO: Debug v1 field ordering/encoding vs Kafka protocol specification 🎉 EVIDENCE OF SUCCESS: - 'DEBUG: API 3 (Metadata) v0' (correct version negotiation) - 'WriteMessages succeeded!' (end-to-end produce works) - No UNSUPPORTED_VERSION errors in logs - Clean error handling for invalid API versions IMPACT: This establishes a production-ready foundation for protocol compatibility. Different Kafka clients can negotiate appropriate API versions, and our gateway gracefully handles version mismatches instead of crashing. Next: Debug Metadata v1 format issue and expand version support for other APIs.	3 months ago
