Amazon’s S3 service seems to be getting into everything ‘online’ these days. Here’s an announcement by Mark Atwood of a S3 storage engine for MySQL 5.

It allows one to view and manipulate Amazon’s S3 storage service as
tables and items by MySQL. You can keep your blobs or large varchars
or truely huge datasets in S3, and then join the tables against your
local ones.
