#Tusker - Redis Based Distributed Task Locking

##Why? Let's look at following scenario

• We receive chunks of ogg's to encode into different servers
• All of those are related to single stream
• And we also receive the end of the stream too
• Now we need to notify back, after all the chunks are encoded

##Do it with Tusker

###When we are encoding chunks

var tusker = require('tusker');
var taskManager = tusker.initialize();

//when we are begin to encode a chunk
var lockname = "" + Math.random();
taskManager.lock('the-task', lockname);

//after we do the encoding
taskManager.unlock('the-task', lockname);

###When we are closing the stream

var tusker = require('tusker');
var taskManager = tusker.initialize();

var info = { some_data: 10 };
taskManager.close('the-task', info);

###Receive notification after every chunk is encoded

taskManager.watchForReleased(function(err, taskName, info, watchAgain) {

//merge chunks and notify back
watchAgain();

});
