Hi! The way that the JIRA issue you linked will achieve this is by hooking into the network stream pipeline directly, and encrypt the raw network byte stream. We built the network stack on Netty, and will use Netty's SSL/TLS handlers for that.
That should be much more efficient than manual encryption/decryption in each user function.
