Weston Pace updated ARROW-14356:
--------------------------------
Description:
It is difficult to calculate the size (in bytes) of an array that has offsets
because offsets are "# of values" there is no type-erased way to known how many
bytes each value occupies.
was:
It is difficult to calculate the size (in bytes) of an array that has offsets
because offsets are "# of values" there is no type-erased way to known how many
bytes each value occupies.
This could be handled somewhat manually with a visitor.
Summary: [C++] Create kernel to determine buffer memory "referenced" by
arrays (even if there are offsets) (was: [C++] Improve array size estimation
to account for offsets)
