Once we have Redis up and running, we want to be able to interact with it. But today, it is easy as pulling a Docker image and running it.
#Asp.net core private cache install
In the past, we would have to download and install Redis and go through the entire process of setting it up and so on. With the rise of Docker, we no longer have to install 3rd party applications we want to interact with from our applications. Regardless of which implementation you choose, the app interacts with the cache using the IDistributedCache interface. There are many different ways to implement this in our ASP.NET microservice (Memcached, Redis, Cassandra, Elasticache, etc). In the cloud crazed world, we live in today, this is a no brainer for any application looking to implement a reliable caching strategy.Įither this or have all your data saved in a single server with tons of memory likely to die on you at a moment's notice and have your smooth-running application thrown into disarray. This way, you can also ensure that that app restarts, or in the case of having to restart your app server will not result in the loss of your caching data. The advantages of having a distributed cache are being comfortable in knowing that your data is coherent – that it is consistent across all nodes of your application. If a key exists in the cache, you don’t do a database query.Ī distributed cache is as its name says, caching with the added benefit of having it distributed across multiple servers. When you want to load something from the database, you first check whether the cache doesn’t have an entry with that key (based on the ID of your database record, for example). The cache is structured around keys and values – there’s a cached entry for each key. For this, we look to a different, but same, solution. This sounds pretty trivial if you have your application and run it on a single server, but in this cloud-first, auto-scale landscape we are living in, suddenly it’s not as simple. A cache is a temporary storage area, usually in memory.
It is the process of storing frequently accessed information in a cache. HomeController.This post was originally posted on my website at Ĭaching is one of those things that in most cases, are probably inevitable with any project, especially if your project is a web application. If no one accesses the page for more than three seconds, the cache will expire. If any user accesses the page within three seconds it will be active. This indicates how long the cache should be idle. Also, the SetSlidingExpiration option is set in the example.
In coding, the TryGetValue method checks if there is any cached content for the keyword ‘CacheDateKey’, which will provide content if there is any cached content in it. You can see in the controller constructor IMemor圜ache object has been passed. Here the IMemor圜ache interface is implemented using dependency injection. Instead of creating content, the cache will hold the content, so it will be available quickly.ĪSP.NET Core support IMemor圜ache, its cache storage in the memory of the webserver. You can use cache for rarely changing content. Instead of generating the content, you can retrieve the content from the cache. You can improve the performance of your application by using cache.
