Subject What should the "Graphical Query Explainer" shows?
Date Fri, 28 May 2010 13:29:53 GMT
Hi All,

I like to get your ideas on what should the "Graphical Query Explainer"
convey to a viewer? Of course we can enhance as more information needed
later.
But it's better to put up the most important information.

I've thought of including following after some thinking and also after
referring to PostgreSQL's graphical query explainer.


   - Statement executed
   - Type of scan performed (eg: TABLESCAN, INDEXSCAN, PROJECTION)
   - Estimated cost by the Optimizer
   - Estimated rows by the Optimizer
   - Sort/Scan type

Your comments/thoughts would be nice.

Thanks.
