Question: Adding example for reordering out of order messages

[1123]

I recently came across this question: https://groups.google.com/forum/#!topic/confluent-platform/5NrqRz-GITk . Would it make sense to contribute an example stateful transformer to achieve this in this repository?

@1123 : If you'd like to contribute such a stateful example, then this would be great!

I sketched up an example for reordering using stateful transformer.
Would be glad to discuss.

Hi, @sshcherbakov would you consider contributing this to https://github.com/confluentinc/kafka-tutorials?
I can help you with the tutorial writing process if you want.

PR: #411

[sshcherbakov]

Thank you @bbejeck and apologies for delay in response.
I checked with my employer and it seems that I may contribute to https://github.com/confluentinc/kafka-tutorials

Thanks @bbejeck, @mjsax for the thorough review, I'll correct. Btw. there might be an issue with the not fixed time zone. I'll try to improve that as well.

Should we still merge #441 or move directly to a kafka-tutorials contribution? No harm to merge, but the examples repo is superseded with the tutorial so not sure how much sense it makes to add to ti?

[bbejeck]

If @sshcherbakov is willing to do a tutorial then I'd say move it to a kafka-tutorials contribution. I'll leave it to @sshcherbakov if he wants to close #411.

@sshcherbakov if you have any questions or need any help feel free to reach out to me.

I hope to have addressed all comments and updated PR.
Also fixed time zone to UTC and made a couple of minor simplifications.
