KTable was developed before the SWT Table got the VIRTUAL extension to 
solve exactly this issue. Now that the SWT Table can also be virtual, 
KTable's strength lies more in non-database-related features like fancy 
selection modes, custom cell renderers, cell spanning etc.

I use KTable with MySQL (actually wrote it for that purpose). My 
TableModel uses a scrollable ResultSet. My average customer has about 
1000 records with up to ten (not very active) users connected to the 
server and the performance is very good. There is a short delay when 
fetching the first record but this seems to be nearly independent of the 
number of records in the table.

If you are not sure whether you need caching or not, I would suggest a 
simple implementation using SWT Table or KTable first and then, if it 
fails to please, put more tuning effort into it later. I would say that 
KTable gives you more flexibility for the Data-View Interface, but if 
you started with SWT table, this might be the way for you to go.

Friederich
