Subject [jira] Created: (DERBY-716) Re-enable VTIs
Date Fri, 18 Nov 2005 00:14:41 GMT
Re-enable VTIs
--------------

         Key: DERBY-716
         URL: http://issues.apache.org/jira/browse/DERBY-716
     Project: Derby
        Type: New Feature
    Reporter: Rick Hillegas


Cloudscape used to expose Virtual Table Interfaces, by which any class which implemented ResultSet
could be included in a query's FROM list. Derby still exposes a number of these VTIs as diagnostic
tools. However, Derby now prevents customers from declaring their own VTIs. The parser raises
an error if a VTI's package isn't one of the Derby diagnostic packages.

This is a very powerful feature which customers can use to solve many problems. We should
discuss the reasons that it was disabled and come up with a plan for putting this power back
into our customers' hands.
