I was wondering if there are any obvious pros and cons one should be aware about, while choosing to use a Binary type as a primary key, while being RANDOMIZED.
Which means, new inserts will have random 4 bytes as their PK – versus having a sequence of type Integer?
I’m using MySQL/MyISAM.
Thanks,

If the primary key isn’t sequential then insert performance for a clustered index will not be very good. It has to rearrange the index for almost every insert.
