Async Get<T> (and others) Operation

[fernandozago]

Hello guys.

I'm doing some research on distributed memory caching using NCache. Its really a great product. Thank you for that.

But i'm experiencing some dificulties about getting data out of the cache to my application. Especifically async calls.

Thats what I got.

(My Application) <-> (NCache Cluster (3 nodes)) <-> (SqlServer)

I'm choosing the option of Read-Thru and looking up to the database for the keys that is not existing on the cache. It is a remote database that sits on the cloud, and its taking about ~5ms to bring down the data from the sqlserver to the cache and then the app (~5ms across all that).

After that (db lookup) its doing really fast because i'm using the Client Cache (In-Proc isolation) to speed things up...

My concern is that, Get<T> isn't async. so it locks my application for (5ms).

Any takes on that ?

Update: I fixed that issue adding this extension for the Get<T> calls, but it's almost certainly not a good code because i'm not taking advantage of a "in-memory" calls when using a cache isolation in-proc when the data already on the cache.

Taking advantage of the ValueTask<T> for the GetAsync<T> operation should perform better.

public static class ICacheExtensions
    {
        public static Task<T> GetAsync<T>(this ICache cache, string key)
        {
            return Task.Run(() => cache.Get<T>(key));
        }
    }

Thank you.
