 One of the commonly implemented recipes using this software is a work queue.  http://www.rabbitmq.com/tutorials/tutorial-four-java.html
describes the use case where
 
 * A producer sends a message with a routing key. 
-* The message goes to the queues whose binding key exactly matches the routing key of the
message.	
+* The message is routed to the queue whose binding key exactly matches the routing key of
the message.	
 * There are multiple consumers and each consumer is interested in processing only a subset
of the messages by binding to the interested keys

 While this works, in production systems one needs the following

 * Ability to handle failures: when a consumers fails another consumer must be started or
the other consumers must start processing these messages that should have been processed by
the failed consumer.
 * When the existing consumers cannot keep up with the task generation rate, new consumers
will be added. The tasks must be redistributed among all the consumers. 
 
-In this sample app, we explain how these set of consumers can be grouped together and handle
consumer failures and expansion automatically.
+In this recipe, we demonstrate handling of consumer failures and new consumer additions using
Helix.
 
 Mapping this usecase to Helix is pretty easy as the binding key/routing key is equivalent
to a partition. 
 
-Lets take a real example. Lets say a topic has 6 partitions, and we have 2 consumers to process
all the queues. 
+Let's take an example. Lets say the queue has 6 partitions, and we have 2 consumers to process
all the queues. 
 What we want is all 6 queues to be evenly divided among 2 consumers. 
 Eventually when the system scales, we add more consumers to keep up. This will make each
consumer process tasks from 2 queues.
-Now let's say that a consumer fails and that the number of active consumers is now reduced
to 2. This means each consumer must process 3 queues.

as the pub/sub system one can extend this solution to other pub/sub systems.
