Hey James, all of the primitive Array types that store their data as a contiguous array have a function which can return that array. For example, if you have an *array.Date32 you can use the Date32Values() method as shown here: https://pkg.go.dev/github.com/apache/arrow/go/[email protected]/array#Date32.Date32Values The same would be true for all of the other primitive types such as the int and uint types.
You would still have to consult the validity bitmap in order to tell whether a particular index is null either via the IsNull method. In most cases the overhead from calling Value(i) instead of just iterating over a slice is negligible.

It seems like it would be most efficient if I could get a contiguous array of values to loop through, but as far as I know the array interface only exposes the ith value via Value(i). Is there a different way to loop over the values?
