Critically, the data structures offer APIs to access to the internal contiguous memory buffers in each array:
e.g. https://github.com/apache/arrow/blob/master/cpp/src/arrow/types/primitive.h#L89 That the library operates with contiguous arrays as primitive unit of data is what makes the access paths "vectorized" / "array-oriented" versus "scalar" (one value at a time). - Wes On Tue, Aug 9, 2016 at 8:44 AM, Philip <brann...@gmail.com> wrote: > Hi Sanjay, > > Vectorized access is in many places.
