When and how will Value objects be constructed, what structure or
object will own them and at what stage of query processing will
ownership of data be transferred? What about Item_subselect or
Item_ref derivatives? How will Item references handle data ownership
And all this to improve copying of BLOBs? One of the key strengths
of MySQL is the ability to do entire BLOB processing by reference,
without reading or copying.... Is this part of the newly announced
MySQL reengineering initiative?
