When using a JVM engine, Scala UDFs have an advantage over Python UDFs because data doesn't have to be shifted out to the Python environment for processing. If I understand the implications of using the Photon C++ engine, any processing that needs to...
Photon does not support UDFs:https://learn.microsoft.com/en-us/azure/databricks/runtime/photon#limitationsSo when creating a UDF, photon will not be used.

As Some VM's /DBU's reservations are purchased, however, it was underutilized. How can we optimize the underutilization? Do we have any guidelines or best practices?
We have 5 reserved instances of Azure VMs to run the data bricks cluster jobs. And this is not being utilized efficiently (as per the usage metrics – 1 of the reservation is 10-15% utilized and the other one is 30-40% utilized). Could you please help...
