logging.py

Purpose: Structured JSON logging for cloud-native deployment

Functions:

• setup_logging(level: str) - Configure JSON logging with stdout handler
• get_logger(name: str) - Get logger instance with JSON formatter
• with_correlation_id(correlation_id: str) - Add correlation ID to log context
• clear_correlation_id() - Clear correlation ID context

Usage:

from core.logging import get_logger, with_correlation_id

logger = get_logger(__name__)
logger.info("Processing request", extra={"extra_fields": with_correlation_id("req-123")})

Log Format:

{
  "timestamp": "2025-01-27T10:00:00Z",
  "level": "INFO",
  "logger": "backend.api.tasks",
  "message": "Task created successfully",
  "module": "tasks",
  "function": "create_task",
  "line": 42,
  "correlation_id": "req-123"
