Hans Zeller commented on TRAFODION-1983:
----------------------------------------
The issue is that we need to replace the VEG expression in the key predicate
when we want to compute the number of active partitions at compile time. This
is done with compile-time expression evaluation, which does not allow VEG
expressions.
