Dumindu Buddhika commented on PHOENIX-1875:
-------------------------------------------
If we do so, in appending null to a fixed width array, we should identify
whether the base type is of primitive and then append/prepend a default value(0
for numeric types and false for boolean) to the array? Is this the proper way
to go?
> implement ARRAY_PREPEND built in function
