"""Caching module for Portfolio Intelligence Platform.

This module provides production-ready caching infrastructure with:
- Hybrid caching (Redis primary, in-memory fallback)
- Domain-specific TTL strategies for financial data
- Event-driven cache invalidation
- Cache warming capabilities
- Comprehensive monitoring and statistics

Example:
    Basic usage with HybridCache:

    >>> from backend.caching import HybridCache, FinancialDataCacheManager
    >>> from backend.config import settings
    >>>
    >>> cache = HybridCache(
    ...     redis_url=settings.upstash_redis_url,
    ...     redis_token=settings.upstash_redis_token,
    ... )
    >>> manager = FinancialDataCacheManager(cache)
    >>>
    >>> # Cache market data
    >>> manager.cache_market_data("AAPL", {"price": 150.00, "volume": 1000000})
    >>>
    >>> # Retrieve cached data
    >>> data = manager.get_market_data("AAPL")
    >>>
    >>> # Get statistics
    >>> stats = manager.get_stats()
    >>> print(f"Hit rate: {stats.hit_rate:.2f}%")
