Browsing the activerecord-2.1.0 source code I found the following:
The mysql adapter of activerecord is now able to use more appropriate
data types for integers! Finally! That's awesome!
However, where is the mediumint data type? Numbers with length of 5 and
6 should be stored as a mediumint in order to obtain optimal performance
Shouldn't this be fixed somehow? I'm considering applying a patch myself
(however, I don't know how yet), but I thought I'd hear you guys out
Thanks in advance.
