The "Basic Optimizer" in issue #46 will simply cache some basic data dictionary
information with a
query.
The "Optimizer" in issue #45 will allow a one-table query to be written in
standard SQL.
This is the third step, a "JOIN optimizer," would allow multi-table joins.
The join optimizer might never be written. There are, in fact, many reasons
not to have a join
optimizer. Foremost, MySQL already has one.
