Use azure table storage for AspNet core 1.0 Distributed Cache (save money on redis in azure)

AspNetCache-AzureTableStorage

Use azure table storage for AspNet core 1.0 Distributed Cache.

Azure Table Storage is a very cheap, super fast key value store, and its much cheaper than the redis cluster in azure. This is not a true replacement for redis, and redis should be used if people have money, but this is designed to get people a very cheap cache in azure. Currently this doesn't actually support the dotnet core runtime, and won't until the Azure Storage client is updated to support core.

warning As of right now sliding expiration doesn't work. This is at the top of the list to get working

How to use

install-package AzureTableStorageCache

In your startup.cs

 public void ConfigureServices(IServiceCollection services)
        {
            services.AddAzureTableStorageCache("!!!CONNECTIONSTRINGHERE!!!", "tablename", "partitionKey");
            // Add framework services.
            services.AddMvc();
        }

Then in a controller just ask for an IDistributedCache in the constructor. Since this implements Microsoft's IDistributed cache, it could be easily swapped out for redis or another Distributed cache.

public class HomeController : Controller 
{
        private readonly IDistributedCache cacheMechanism;

        public HomeController(IDistributedCache cacheMechanism)
        {
            this.cacheMechanism = cacheMechanism;
        }
        public async Task<IActionResult> Index()
        {
            var data = await cacheMechanism.GetAsync("awesomeRecord");
            var result = string.Empty;
            if(data != null)
            {
                result = Encoding.UTF32.GetString(data);
            }
            return View(result);

        }

        public async Task<IActionResult> AddCache()
        {
            await cacheMechanism.SetAsync("awesomeRecord", Encoding.UTF32.GetBytes("Im Awesome"));
            ViewData["Message"] = "Your application description page.";

            return RedirectToAction("Index");
        }
}
