Kai Zheng commented on ARROW-85:
--------------------------------
Yes I understood. I thought at least we need to be careful about calling the
method directly or indirectly given a large dataset to comare against another.
Would leave this for further investigation and consideration, right now we
don't have much benchmark tests to verify this.
> C++: memcmp is too expensive for Buffer's Equal

> It looks too expensive to use memcmp to compare two buffers. Instead, the
> starting address and length/capacity would be good enough to use. Higher
> level codes relying on memcmp behaviour can be done in higher level.
