Laurent Goujon commented on DRILL-4335:
---------------------------------------

It looks like from the initial implementation that there are lots of byte 
copying involved. Any estimation/benchmark to quantify the impact on 
throughput? wouldn't a SSL/TLS implementation be a more performant alternative 
here (because of its integration directly into netty?)

> Apache Drill should support network encryption

> This is clearly related to Drill-291 but wanted to make explicit that this 
> needs to include network level encryption and not just authentication. This 
> is particularly important for the client connection to Drill which will often 
> be sending passwords in the clear until there is encryption.
