Memcached is a high-performance, distributed memory object caching system. Redakt offers Memcached integration through an optional NuGet package. Memcached is only suitable for very large distributed applications with many nodes. For most applications, the in-memory cache together with a distributed service bus is a better performing setup.


Install the Memcached package with the NuGet package manager or the Package Manager Console.

PM> Install-Package Redakt.Providers.Memcached

Service registration

Register Memcached services in the ConfigureServices() method of your project's Startup.cs file by adding an AddMemcached() call to the Redakt builder instance. The order in which services are added to the Redakt builder is not important.

public void ConfigureServices(IServiceCollection services)
    // ... framework and other services here

    var builder = services.AddRedakt();
    builder.AddMemcached();  // Optionally pass Action<MemcachedCacheOptions> parameter.
    // ... other Redakt services

Configuration settings

The Memcached cache is configured through the appsettings.json file. Any configuration that is not included in the appsettings.json file will be set to its default values. Additionally, an Action<MemcachedCacheOptions> configuration delegate may be passed to the AddMemcached() call. Configuration set through this delegate takes priority and overrides values in the appsettings.json file.
