Wes McKinney commented on ARROW-85:
-----------------------------------
If separate Buffer objects reference the same virtual address segment we should
not call memcmp, I agree. Can you clarify the JIRA scope to optimize for this
special case? If two Buffers reference different memory, we must use memcmp (or
equivalent).
> 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.
