Jeremy Bauer commented on OPENJPA-1530:
---------------------------------------
I agree with Milosz. The property does not go beyond the scope of the
dictionary so it should be localized to the MySQL dictionary. For example:
<property name="openjpa.jdbc.DBDictionary" value="mysql(Engine=ndbcluster)"/>.
You just need to provide a getter and setter (or public field) for "Engine" in
the MySQL dictionary and the config framework will take care of setting the
value. Also, if you add a new dictionary value please update the OpenJPA docs
specific to the MySQL dictionary. Oh, and the print statement needs to be
removed. :-)

> The MySQLDictionary currently supports only TYPE innodb. There is a skeleton
> for support of this element but there is no way to change it from the default.
> Also, according to the MySQL documentation
> http://dev.mysql.com/doc/refman/5.1/en/create-table.html TYPE is deprecated.
> The recommended (and supported) keyword is ENGINE.
> "Since MySQL 5.1.8, it produces a warning. It will be removed in a future
> MySQL release. You should not use TYPE in any new applications, and you
> should immediately begin conversion of existing applications to use ENGINE
> instead."
> I propose to change TYPE to ENGINE, and to provide a way for the user to
> specify which engine to use.
> I need some feedback on this: A property, mysql.engine, with a default of
> innodb (for compatibility) can be specified by the user in order to create
> tables using any of the supported engines. Can the property be put onto the
> command line? Can the property be added to persistence.xml? Can the property
> be added to the maven profile properties?
