Configuration

Settings

To configure RedisMemoryCacheInvalidation, you should use one of the InvalidationManager.ConfigureAsync methods. Three parameters are available to configure it :

  • redisConfig:string : Redis connection string. Check StackExchange.Redis Configuration model for more details. A basic example is localhost:6379.
  • mux:ConnectionMultiplexer : an existing StackExchange.Redis.ConnectionMultiplexer that you want to reuse.
  • settings:InvalidationSettings : see below for more details.

InvalidationSettings is the main configuration object

  • InvalidationStrategy:InvalidationStrategyType : How to handle invalidation notifications : notify ChangeMonitor, execute callback or automatically remove an item from the cache.
  • TargetCache:MemoryCache : the target MemoryCache instance when InvalidationStrategy is set to AutoCacheRemoval.
  • EnableKeySpaceNotifications:bool : allow subscribe to keyevents notification __keyevent*__:.
  • InvalidationCallback:Action : an callback that is invoked when InvalidationStrategy is set to External.

When to configure ?

Thanks to StackExchange.Redis a persistent connection is established between your application and the redis server. That's why it's important to configure it very early at startup : Global.asax, Owin Startup, ... In this way, you won't lose notification messages.
