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

Subpartitioning — also known as composite partitioning — is the further

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

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 :)
