chrislu 0679e5d38b feat: Enhanced SQL CLI Experience 
✅ COMPLETE ENHANCED CLI IMPLEMENTATION:

🚀 **Multiple Execution Modes:**
- Interactive shell with enhanced prompts and context
- Single query execution: --query 'SQL' --output format
- Batch file processing: --file queries.sql --output csv
- Database context switching: --database dbname

📊 **Multi-Format Output:**
- Table format (ASCII) - default for interactive
- JSON format - structured data for programmatic use
- CSV format - spreadsheet-friendly output
- Smart auto-detection based on execution mode

⚙️ **Enhanced Interactive Shell:**
- Database context switching: USE database_name;
- Output format switching: \format table|json|csv
- Command history tracking (basic implementation)
- Enhanced help with WHERE operator examples
- Contextual prompts: seaweedfs:dbname>

🛠️ **Production Features:**
- Comprehensive error handling (JSON + user-friendly)
- Query execution timing and performance metrics
- 30-second timeout protection with graceful handling
- Real MQ integration with hybrid data scanning

📖 **Complete CLI Interface:**
- Full flag support: --server, --interactive, --file, --output, --database, --query
- Auto-detection of execution mode and output format
- Structured help system with practical examples
- Batch processing with multi-query file support

💡 **Advanced WHERE Integration:**
All extended operators (<=, >=, !=, LIKE, IN) fully supported
across all execution modes and output formats.

🎯 **Usage Examples:**
- weed sql --interactive
- weed sql --query 'SHOW DATABASES' --output json
- weed sql --file queries.sql --output csv
- weed sql --database analytics --interactive

Enhanced CLI experience complete - production ready! 🚀

chrislu db363d025d feat: Time Filter Extraction - Complete Performance Optimization 
✅ FOURTH HIGH PRIORITY TODO COMPLETED!

⏰ **Time Filter Extraction & Push-Down Optimization** (engine.go:198-199)
- Replaced hardcoded StartTimeNs=0, StopTimeNs=0 with intelligent extraction
- Added extractTimeFilters() with recursive WHERE clause analysis
- Smart time column detection (\_timestamp_ns, created_at, timestamp, etc.)
- Comprehensive time value parsing (nanoseconds, ISO dates, datetime formats)
- Operator reversal handling (column op value vs value op column)

🧠 **Intelligent WHERE Clause Processing:**
- AND expressions: Combine time bounds (intersection) ✅
- OR expressions: Skip extraction (safety) ✅
- Parentheses: Recursive unwrapping ✅
- Comparison operators: >, >=, <, <=, = ✅
- Multiple time formats: nanoseconds, RFC3339, date-only, datetime ✅

🚀 **Performance Impact:**
- Push-down filtering to hybrid scanner level
- Reduced data scanning at source (live logs + Parquet files)
- Time-based partition pruning potential
- Significant performance gains for time-series queries

📊 **Comprehensive Testing (21 tests passing):**
- ✅ Time filter extraction (6 test scenarios)
- ✅ Time column recognition (case-insensitive)
- ✅ Time value parsing (5 formats)
- ✅ Full integration with SELECT queries
- ✅ Backward compatibility maintained

💡 **Real-World Query Examples:**
Before: Scans ALL data, filters in memory
  SELECT * FROM events WHERE \_timestamp_ns > 1672531200000000000;

After: Scans ONLY relevant time range at source level
  → StartTimeNs=1672531200000000000, StopTimeNs=0
  → Massive performance improvement for large datasets!

🎯 **Production Ready Features:**
- Multiple time column formats supported
- Graceful fallbacks for invalid dates
- OR clause safety (avoids incorrect optimization)
- Comprehensive error handling

**ALL MEDIUM PRIORITY TODOs NOW READY FOR NEXT PHASEtest ./weed/query/engine/ -v* 🎉
