I see you've been burning the midnight oil.

 Subject: [discuss] using deep learning to improve Spark
   
Hi all,
Hope you all enjoyed the Tesla 3 unveiling earlier tonight.
I'd like to bring your attention to a project called DeepSpark that we have been working on
for the past three years. We realized that scaling software development was challenging. A
large fraction of software engineering has been manual and mundane: writing test cases, fixing
bugs, implementing features according to specs, and reviewing pull requests. So we started
this project to see how much we could automate.
After three years of development and one year of testing, we now have enough confidence that
this could work well in practice. For example, Matei confessed to me today: "It looks like
DeepSpark has a better understanding of Spark internals than I ever will. It updated several
pieces of code I wrote long ago that even I no longer understood.”

I think it's time to discuss as a community about how we want to continue this project to ensure
Spark is stable, secure, and easy to use yet able to progress as fast as possible. I'm still
working on a more formal design doc, and it might take a little bit more time since I haven't
been able to fully grasp DeepSpark's capabilities yet. Based on my understanding right now,
I've written a blog post about DeepSpark here: https://databricks.com/blog/2016/04/01/unreasonable-effectiveness-of-deep-learning-on-spark.html

Please take a look and share your thoughts. Obviously, this is an ambitious project and could
take many years to fully implement. One major challenge is cost. The current Spark Jenkins
infrastructure provided by the AMPLab has only 8 machines, but DeepSpark uses 12000 machines.
I'm not sure whether AMPLab or Databricks can fund DeepSpark's operation for a long period
of time. Perhaps AWS can help out here. Let me know if you have other ideas.
