Hi Eric,
Sorry to interfere at that point but I cannot let you using my name and
Netflix together for Chukwa.
I've designed Chukwa and I'm the main architect behind Chukwa, correct.

However Netflix is NOT running CHUKWA but HONU.
Honu is a stream based data collection that run at scale at Netflix and
other places.
I've designed Honu when I was at Netflix and Honu does not use CHUKWA code
Honu code is a complete rewrite done by me and only me and that's the
reason why Honu scale
to more than 60 billions events/day.
People are still using the name Chukwa because it was the name I used for
my first presentation.
I've changed the name to Honu when I started the complete rewrite and you
are aware of that.

I'm the architect of both so there's some similarities but
Chukwa will never be Honu and I cannot let people think that they are.

I'll ask Kurt to update his presentation and to use the correct name: HONU
and not CHUKWA.

You can read more about Honu:

Sorry Eric and next time you use my work please verify your sources or I'll
have to take
a more active role.
