On the other hand, these optimizations themselves need to be sufficiently inexpensive to justify their own processing cost over the gains they bring.

Partitioning is a way in which a database (MySQL in this case) splits its actual data down into separate tables but still gets treated as a single table by the SQL layer. Otherwise, the storage engine does a scatter-gather and queries ALL partitions in a UNION that is not concurrent. So, What is MySQL Partitioning?
