 Description   

The DatabaseStore holds an in-memory copy of Databases and there is the functional VDBRepository copy as well. String canonicalization in the metadata objects should help with reducing the memory footprint, but it may be good to go further and use clones of the functional metadata on demand.

Placing into 9.3 with the initial idea of getting a preview release into JDV 7.x, but the parent issue is still targeted to 10.

Moving to 10 as we've limited the ddl work for 9.3 and these are applicable to the larger changes to allow interactive ddl processing.

The older changes on which this issue was based were not yet brought forward.
