Description

This ticket is to track the work on adding the ParDo async API. The motivation for this is:

• Many users are experienced in asynchronous programming. With async frameworks such as Netty and ParSeq and libs like async jersey client, they are able to make remote calls efficiently and the libraries help manage the execution threads underneath. Async remote calls are very common in most of our streaming applications today.

• Many jobs are running on a multi-tenancy cluster. Async processing helps for less resource usage and fast computation (less context switch).

This API has become one of the most asked Java api from SamzaRunner users.
