-## Error Handling Strategy
-
-### Connection Management Errors
-- Automatically re-establish connections when they fail
-- Proper waiting and timeout handling when connection pool is exhausted
-- Graceful degradation when database is unavailable
-
-### SQL Execution Errors
-- Detailed error reporting for SQL syntax errors
-- Clear messages for constraint violation errors
-- Automatic cancellation of timeout queries
-
-### Concurrency Safety
-- Thread-safe connection pool operations
-- Concurrency-safe query builder design
-- Proper locking mechanisms to prevent race conditions
-
-## Performance Features
-
-### Connection Pool Optimization
-- Pre-established connections reduce creation overhead
-- Connection reuse improves overall performance
-- Automatic connection health checks
-
-### Query Optimization
-- Prepared statement reuse mechanism
-- Automatic slow query logging and analysis
-- Query execution time monitoring
-
-### Memory Management
-- Efficient query builder memory usage
-- Automatic release of unused connections
-- Streaming result set processing support
