Hi Zoltan, I'm not feeling brave enough to continue cc'ing a bunch of other Apache projects just yet, but I did leave a comment in your gdoc describing what Kudu currently supports and what we could offer in the future.
It wasn't clear if you wanted to carry out this discussion over gdoc comments or over e-mail; if the latter please let me know and I'll respond to your original e-mail (including all the other mailing lists this time) with my comment.
