Abstract:

Repo: https://github.com/mysql/mysql-server

Patch on top of 5.6.35: https://github.com/mysql/mysql-server/tree/d61eb03ba1b8478d6cb09969ca6c38f330a93178

This diff adds a generic protocol option to modify the compression algorithm at connect time. This is done using the 'compression_lib' connection attribute, which when combined with the compress flag, will determine a new compression library for network compression. It is meant to be extendable to other compression libraries.

When a client wants to use compression, they can either set the compress flag as they do now, or use mysql_options to select a compression library from the given enums. Under the hood, this will set the compress flag and pass the library through to the server via a connection attribute.

How to repeat:
