Redis pub/sub channel listener should execute messages parallely.

[Prashant-Thorat]

Hi for my chatting application I'm planning to use the redis pub/sub for server scalability. wanted to use Redis pub/sub for broadcasting messages between servers.

`
String redisUrl = "redis://" + host + ":" + port;
redisClient = RedisClient.create(RedisURI.create(redisUrl));
syncPool = redisClient.connect();
isRunning = true;

StatefulRedisPubSubConnection<String, String> connection = redisClient.connectPubSub();
RedisPubSubAsyncCommands<String, String> async = connection.async();

async.subscribe("messages");
connection.addListener(new RedisMessageHandler());
`

RedisMessageHandler is processing messages in sequential manner(i.e. one after another). but I wanted to send received message in parallel.

Redis itself is single-threaded and the connection protocol is sequential. You can still offload work to a Executor from your listener to unblock the event loop.
