Amazon ElastiCache Cluster Configuration is an enhanced .NET library that supports connecting to an Amazon ElastiCache cluster for Auto Discovery. This client library is an extension built upon Enyim and is released under the Apache 2.0 License.

To use Amazon ElastiCache with Auto Discovery, the ElastiCacheClusterConfig object must be passed to the MemcachedClient object. An ElastiCacheClusterConfig can be created from the App.config if there is a clusterclient section or you can pass a different section.

var client = new MemcachedClient(new ElastiCacheClusterConfig());

ElastiCacheClusterConfig can also be instantiated by providing it an AutoConfigSetup or simply provide the hostname and port like so:

var client = new MemcachedClient(new ElastiCacheClusterConfig("hostname", 11211));

Once instantiation occurs in this way, MemcachedClient can be used the same way as the Enyim Client. The only difference is a background process polls the cluster and updates nodes when changes occur.

The ElastiCacheClusterConfig object can be configured from an application's App.config file. Here is a sample App.config that configures the Amazon ElastiCache configuration URL and the polling interval at which the client will check for changes to the cluster.

<clusterclient>
  <endpoint hostname="my-configuruation-url.cache.amazonaws.com" port="11211" />
  <poller intervalDelay="60000" />
</clusterclient>
