A fast, robust hybrid cache for .NET with advanced resiliency features like fail-safe, cache stampede protection, and multi-level caching.
FusionCache is a hybrid caching library for .NET that provides both in-memory and optional distributed caching layers. It solves common caching problems like cache stampedes, cold starts, and transient failures by incorporating advanced resiliency features such as fail-safe mechanisms, timeouts, and real-time synchronization between nodes.
.NET developers building high-performance, scalable applications that require robust caching solutions, especially those dealing with distributed systems or high-volume traffic.
Developers choose FusionCache for its comprehensive set of resiliency features, seamless hybrid caching support, and production-ready reliability, which are often missing in other caching libraries. Its compatibility with Microsoft's HybridCache and extensive observability tools make it a versatile choice for modern .NET applications.
FusionCache is an easy to use, fast and robust hybrid cache with advanced resiliency features.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Includes cache stampede protection, fail-safe mechanisms, and auto-recovery, as documented in the Resiliency section, addressing real-world production challenges like transient failures.
Supports both in-memory (L1) and any IDistributedCache implementation (L2), enabling better cold starts and scalability, with transparent multi-level caching shown in the diagram and features list.
Provides native OpenTelemetry integration, logging, and events for monitoring, detailed in the Observability section, making it easy to track cache performance and issues.
Used in production for years, handling billions of requests, and adopted by Microsoft in products like Data API Builder, as highlighted in the README.
With numerous options, plugins, serializers, and backplanes, initial setup and tuning can be overwhelming for straightforward caching needs, requiring deeper investment.
Relies on multiple NuGet packages for features like serializers and backplanes, which can lead to version conflicts and increased maintenance, as seen in the packages table.
Advanced features like fail-safe, timeouts, and backplane synchronization introduce additional latency and resource usage compared to simpler caching solutions, potentially affecting lightweight applications.
