This would be something like:

create table foo () partition by ...

Partitioning by HASH is used primarily to ensure an even distribution of

Partitioning by key is similar to partitioning by hash, except that

Subpartitioning — also known as composite partitioning — is the further
division of each partition in a partitioned table. (partitions that have
partitions)

For reference I am directly apply my fair use rights to the above per
the MySQL development docs. Reference below:

http://dev.mysql.com/doc/refman/5.1/en/partitioning.html

Yes I am fully aware that we don't need to do something just because
MySQL does it. However, Oracle has similar functionality and I would
like to see us keep up :)

Of course I would like it to be done correctly :)
