Subject Re: Discussion on requirements for Data Encryption functionality in Kafka (KIP-317)
Date Tue, 02 Oct 2018 23:58:52 GMT
Hi Sönke,

I would be very interested in participating in this conversation.  Very interested in how
TDE might work in Kafka!  I’m coming with several colleagues and will see if they’re interested
in participating as well.
