No. Things like walking through the table to delete parts of it, or to study the values. As I say, subtle.

Because of the eventual size of the table (and other issues), your testing should get a lot closer to the eventual size. We are seeing some issues now, but there may be bigger issues as it grows. The insertion rate going from 5M -> 50M scares me the most. (Hence, I have dwelled on it.) Having all the activity in a single partition that is 1% of the total makes it all feasible.

The concern over the binlog may be solved via RBR.
