Subject RE: connect db for0.5/0.6

I still think how to design PE as DB output results, you know if too much PE instances connect
DB, cause the connection bottle neck, does it must be singleton PE?

But if the PE not the final results, how design DB PE to connect DB?

There is very little code in common between 0.3 and 0.6, and the feature you mention is not
available off-the shelf with S4 0.6. Does not seem to hard to add though.
