datarouter-memcached

datarouter-memcached is a simple client that implements the MapStorage interface with a Memcached cluster. It can also serve as the basis for implementing cloud provider Memcached implementations, like Amazon's Elasticache.

Installation with Maven

<dependency>
	<groupId>io.datarouter</groupId>
	<artifactId>datarouter-memcached</artifactId>
	<version>0.0.125</version>
</dependency>

Client configuration

There are two ways to configure the client options.

  1. Configuration in a datarouter-properties file.
client.myClient.type=memcached
client.myClient.memcached.numServers=1
client.myClient.memcached.server.0=localhost:11211
  1. Configuration in the code You can define the client options in the code using the MemcachedClientOptionsBuilder and add the ClientOptionsBuilder to the app's WebappBuilder.
Properties properties =  MemcachedClientOptionsBuilder(clientId)
		.withNumServers(1)
		.withServerIndexAndInetSocketAddress(0, "localhost:11211")
		.build();

Monitoring

datarouter-memcached includes a monitoring page to view statistics about client operations (get_hits, get_misses, evictions, etc) on each server. Navigate to it by selecting your memcached client name on the datarouter homepage.

Local Testing

To build this module locally, add memcached.properties to /etc/datarouter/test.
