Subject Re: Discussion on requirements for Data Encryption functionality in Kafka (KIP-317)
Date Mon, 08 Oct 2018 12:00:24 GMT
Hi Mike,

that sounds good! I've not yet received any other feedback, but worst case
scenario is that just the two of us discuss this over a cup of coffee :)

I'll talk to the Summit organizers again about some sort of venue and get
back to you once I know more. Maybe we can get a few more people to join
the discussion once some more details are known.

Other than that, I am also very happy to gather feedback on the mailing
list from people who won't be able to make it to the Summit. So anybody who
can come up with some thoughts or requirements around encryption
functionality for Kafka, please don't hesitate to chime in!

Best regards,
Sönke
