Yes - the get_*_data_point routines *will* be called for each request,
working through some internal representation of the table. The caching
routines are used to load (or release) this internal representation
from some underlying subsystem.

A SET request (such as used to create a new row) would invalidate the
cache, so it would then be re-loaded from the underlying system.
It's up to the SET-handling code in the handler routine to update
this underlying system with the new row.
