As a Google Intern at Hyderabad, I got introduced to a couple of really cool libraries ( TensorFlow  and  FlumeJava ) that use the so called  Deferred Execution Model . I found some very interesting similarities between the two libraries and in this blog post, I'll seek to discuss on how deferred execution works by taking instances from the two libraries. I'll also discuss the pros and cons of Deferred Execution . What is Deferred Execution ?
