Description

When the Int64Builder is used in a context without BigNum, appending two numbers combines them into a single Int64:

> v = Arrow.Builder.new({type: new Arrow.Int64()}).append(1).append(2).finish().toVector()
> v.get(0)
Int32Array [ 1, 2 ]

Whereas the same process with BigNum creates two new Int64s.
