Hello,

The following article is a very good look at some of our limitations and 
highlights some of the pains many of us have been working "around" since 
we started using the software.

https://eng.uber.com/mysql-migration/

Specifically:

* Inefficient architecture for writes
* Inefficient data replication
* Issues with table corruption
* Poor replica MVCC support
* Difficulty upgrading to newer releases

It is a very good read and I encourage our hackers to do so with an open 
mind.

Sincerely,

JD
