Hello,
I have tested this change on a codfw slave of s3 and it took 4 seconds.
After doing a select count on the table and after the first ALTER, a second alter took 3 seconds.
We can probably go ahead and do the ALTER directly on the master one day early in the morning. The s3 slowest slaves (64G) might take a couple of seconds more I guess /cc @jcrespo
The table is pretty tiny, only 68M on disk.
