Description
Is your feature request related to a problem or challenge?
Currently, NullState allocates a boolean buffer for (group) accumulators that potentially has null values.
Describe the solution you'd like
We can optimize it for cases the input columns has no null values, avoiding allocating / resizing the buffers and setting the bits, making the code more efficient and saving some memory.
Describe alternatives you've considered
