The code would need to be cleaned up. I would look to the other examples,
add comments, remove unused code, change anonymous inner classes to be static
inner classes, etc. There is also the question, what makes a good Flink
example? Single-threaded programs
[1](http://primesieve.org/segmented_sieve.html) and
[2](http://sweet.ua.pt/tos/software/prime_sieve.html) can sieve 10^9 numbers in
under 1 second. I think we are better off with batch examples that demonstrate
Flink's performance (such as processing sparse datasets).
If you are interested in adding to the existing examples that would be a
good discussion for the
[dev](https://flink.apache.org/community.html#mailing-lists) mailing list. I
also expect that more users are reading the online documentation than
inspecting the examples so that is another opportunity for contributions.
