chrislu	593c1ebef2	fix: Resolve High Priority TODOs - Real MQ Broker Integration ... ✅ COMPLETED HIGH PRIORITY TODOs: 🔧 **Real FilerClient Integration** (engine.go:131) - Implemented GetFilerClient() method in BrokerClient - Added filerClientImpl with full FilerClient interface compliance - Added AdjustedUrl() and GetDataCenter() methods - Real filerClient connection replaces nil fallback 🔧 **Partition Discovery via MQ Broker** (hybrid_message_scanner.go:116) - Added ListTopicPartitions() method using topic configuration - Implemented discoverTopicPartitions() in HybridMessageScanner - Reads actual partition count from BrokerPartitionAssignments - Generates proper partition ranges based on topic.PartitionCount 📋 **Technical Fixes:** - Fixed compilation errors with undefined variables - Proper error handling with filerClientErr variable - Corrected ConfigureTopicResponse field usage (BrokerPartitionAssignments vs PartitionCount) - Complete FilerClient interface implementation 🎯 **Impact:** - SQL engine now connects to real MQ broker infrastructure - Actual topic partition discovery instead of hardcoded defaults - Production-ready broker integration with graceful fallbacks - Maintains backward compatibility with sample data when broker unavailable ✅ All tests passing - High priority TODO resolution complete! Next: Schema-aware message parsing and time filter optimization.	2025-08-31 21:12:08 -07:00
chrislu	fe41380d51	feat: Phase 2 - Add DDL operations and real MQ broker integration ... Implements comprehensive DDL support for MQ topic management: New Components: - Real MQ broker connectivity via BrokerClient - CREATE TABLE → ConfigureTopic gRPC calls - DROP TABLE → DeleteTopic operations - DESCRIBE table → Schema introspection - SQL type mapping (SQL ↔ MQ schema types) Enhanced Features: - Live topic discovery from MQ broker - Fallback to cached/sample data when broker unavailable - MySQL-compatible DESCRIBE output - Schema validation and error handling - CREATE TABLE with column definitions Key Infrastructure: - broker_client.go: gRPC communication with MQ broker - sql_types.go: Bidirectional SQL/MQ type conversion - describe.go: Table schema introspection - Enhanced engine.go: Full DDL routing and execution Supported SQL Operations: ✅ SHOW DATABASES, SHOW TABLES (live + fallback) ✅ CREATE TABLE table_name (col1 INT, col2 VARCHAR(50), ...) ✅ DROP TABLE table_name ✅ DESCRIBE table_name / SHOW COLUMNS FROM table_name Known Limitations: - SQL parser issues with reserved keywords (e.g., 'timestamp') - Requires running MQ broker for full functionality - ALTER TABLE not yet implemented - DeleteTopic method needs broker-side implementation Architecture Decisions: - Broker discovery via filer lock mechanism (same as shell commands) - Graceful fallback when broker unavailable - ConfigureTopic for CREATE TABLE with 6 default partitions - Schema versioning ready for ALTER TABLE support Testing: - Unit tests updated with filer address parameter - Integration tests for DDL operations - Error handling for connection failures Next Phase: SELECT query execution with Parquet scanning	2025-08-31 21:01:23 -07:00
