Exploring HybridCache in .Net 9

As ASP.NET Core continues to evolve, with the release of .NET 9, a new caching mechanism called HybridCache has been introduced, offering a blend of in-memory and distributed caching to address the limitations of traditional caching methods.

What is HybridCache?

HybridCache is a caching library designed to combine the best features of in-memory caching (L1) and distributed caching (L2). This dual-layer approach helps mitigate common issues like cache stampedes and race conditions, ensuring a more robust and efficient caching strategy.

Key Features of HybridCache

• Stampede Protection: Prevents multiple concurrent requests from overwhelming the cache by ensuring only one request fetches the data while others wait for the result.
• Multi-Tier Caching: Utilizes both in-memory (L1) and distributed (L2) caches, balancing speed and storage capacity.
• Configurable Serialization: Offers flexibility in how data is serialized and deserialized, catering to various application needs.
• Tag-Based Eviction: Allows for more granular control over cache invalidation, improving cache management.

Setting Up HybridCache

To get started with HybridCache in your ASP.NET Core application, follow these steps:

Install the Package

?

1	dotnet add package Microsoft.Extensions.Caching.Hybrid

Register the Service

?

1 2	var builder = WebApplication.CreateBuilder(args); builder.Services.AddHybridCache();

public class SomeService {     private readonly HybridCache _cache;       public SomeService(HybridCache cache)     {         _cache = cache;     }       public async Task<string> GetSomeInfoAsync(string name, int id, CancellationToken token = default)     {         return await _cache.GetOrCreateAsync(             $"CacheKey",             async cancel => await GetDataFromTheSourceAsync(name, id, cancel),             cancellationToken: token         );     }       private async Task<string> GetDataFromTheSourceAsync(string name, int id, CancellationToken token)     {         // Simulate data retrieval         return $"{name}-{id}";     } }

Benefits of HybridCache

• Improved Performance: By leveraging both in-memory and distributed caches, HybridCache reduces latency and enhances data retrieval speed.
• Enhanced Scalability: The dual-layer caching system allows applications to scale more efficiently, handling larger volumes of data without compromising performance.
• Simplified API: HybridCache provides a unified API for both in-process and out-of-process caching, reducing complexity for developers.

Conclusion

HybridCache in .NET Core represents a significant advancement in caching technology, offering a powerful and flexible solution for modern web applications. By combining the strengths of in-memory and distributed caching, it ensures optimal performance, scalability, and reliability.
