Problem: A download excel link should be able to download an excel with any number of records.(usually the total count would vary from 5000 to 500000 or even more.)

Solution: I have decided to use multithreading concept using ExecutorService framework of java 1.7.

I will create thread pool and giving each thread a task , which needs to generate an excel file.
