Description
There is a bunch of MyISAM memory instruments in the performance schema (apparently as inherited from MySQL), but nothing for Aria. Given that we have Aria for system tables and temporary tables, and encourage users to use it rather than MyISAM, I suppose it would be reasonable to have instrumentation for it.
