Description:
Turn on queryeditor logging: -J-Drave.queryeditor=0

Drag/drop a table from the Oracle database on rave-cheetah.  From the new
rowset, open the query editor.

Query editor takes several minutes (!) to start up.  From the log, we can see
that it is loading the metadata (column names) for every table in the database.
 Since there are over 1100, this takes a long time.  

Either this needs to be done in one operation, instead of 1100+, or it needs to
be done lazily.

Evaluation:
See Description.  Need to be smarter about loading metadata.

Evaluation (Entry 2):
This is still a performance issue, but the performance is exactly the same as in
Leopard/Thresher, and this has never been reported by a customer.  Our test
database configuration may be unusual in having so many tables (600-1200), which
is what causes the issue to appear.

We need to be cautious about making changes here, because the current approach
was adopted to address some other, unspecified, problems.

Lowering the priority and severity.
