   > Just a small clarification: my concern regarding N+1 was about network 
latency (round-trips) rather than data volume. Using outputtypehandler allows 
the driver to prefetch LOB data within the same fetch round-trips, whereas 
explicit .read() calls usually force separate network packets for each row.
   
   Hello @henry3260, thank you for clarifying this as I wasn't exactly aware of 
the `outputtypehandler` and it's a valid point.  This is something to think 
about as this would indeed be a nice optimization.
