Node Collector

master

Node Collector is a node module built to collect data from any source, and distribute it to different subscribers.

It's intended to scale across different servers, so you could for example spawn 1 Collectors, and 5 Subscribers in 6 different servers, and as long as they all have the same app_name/app_version, and are connected to the same redis, they will all be synchronized.

If you run 2 or more Collectors in the same app_name/app_version, they will automatically handle a master/slave logic.

When a Subscriber is started, it will automatically receive all previously sent data.

It uses redis to pub/sub operations and storage.

##Usage var collector = new Collector( redis_client, test_app_name, test_app_version, 500, function (saveFn) { saveFn(test_key, test_data); } );

    var subscriber = new Subscriber(
        redis_client,
        redis_client_sub,
        test_app_name,
        test_app_version,
        function (err, data) {
              console.log(data);
            }
        });

    subscriber.startListening();
    collector.startCollecting();
