Javier Luraschi commented on ARROW-3446:
----------------------------------------
Seems reasonable to me, in fact, I think this is already implemented as follows:
{code:java}
uint8, int16, uint16 -> int32
uint32 -> numeric
int64, uint64 -> bit64
{code}
So we can wait on [~romainfrancois] to confirm but this one can probably be
closed.
