Introduction to FusionCache caching
The video starts by explaining a simple example of implementing caching using the FusionCache library, focusing on generating a cache key and a variable for a cacheable DTO.
[00:15]
Using iFusionCache.GetOrSetAsync
The iFusionCache interface exposes a GetOrSetAsync method that allows easy implementation of the cache-aside pattern. The method takes a cache key and a delegate acting as a factory to fetch the value if not present in the cache, such as a typical EF Core query.
[00:27]
Configuring caching options
Caching options can be configured, including cache duration and an optional failsafe. If a null value is returned, the code returns Not Found; otherwise, it returns the value from the controller endpoint.
[00:41]
Performance improvement
If the value wasn't present in the cache on the first request, it will be there for subsequent requests, improving performance.
The video provides a straightforward demonstration of using FusionCache to implement caching in a .NET application, highlighting the simplicity and performance benefits of the cache-aside pattern.

00:41Full Transcript
[00:00] Here's a simple example of how you can implement caching using the Fusion Cache library. I'll start by generating a cache key and a variable to hold my cacheable DTO. The iFusionCache interface exposes a get or set async method,
[00:15] which allows us to easily implement the cache aside pattern. I'll specify the cache key and a delegate that's going to act as a factory to fetch the value if it's not present in the cache. This could be your typical EF core query.
[00:27] you can also configure the caching options such as the cache duration and an optional failsafe if you do end up getting an all value then we can just return not found otherwise we're going to return this value from the controller endpoint and if it wasn't present in the cache on the first
[00:41] request it's going to be there for any subsequent requests which is going to improve our performance
