caching-strategy

An explicit caching strategy in .NET defines an ICachingStrategy interface in the Application layer and a concrete implementation in Infrastructure, applying pattern-based keys and TTL to manage read-heavy workloads. This enforces separation of concerns while controlling data freshness.

Cache invalidation and cache-miss handling in .NET applications are managed through explicit rules defined within the caching strategy. The strategy enforces safe cache-miss handling and explicit invalidation rules to maintain consistent performance and data freshness across varying data volatility.

Yes, the caching strategy approach supports both Redis and in-memory implementations in the Infrastructure layer. By defining an interface in the Application layer, you can swap concrete implementations like RedisCachingStrategy or in-memory caches without altering the application logic.

You should define separate caching strategies when dealing with varying data volatility and read-heavy workloads. Explicit strategies per data access pattern ensure controlled invalidation and TTL-based freshness, preventing stale data while optimizing performance for specific query requirements.

Structure your .NET project by defining caching strategy interfaces in the Application layer and concrete implementations in the Infrastructure layer. This separation of concerns allows query handlers to cache frequently accessed data without coupling application logic to specific cache providers.
