Lars Hofhansl commented on HBASE-7162:
--------------------------------------
The "problem" is KeyValue to getBuffer, which is used quite frequently. But
looking at the useages, most of them just get the buffer to compare the row
portion, or the qualifier portion, etc. So I was thinking that a great start
would be to add a getRowBuffer, getFamilyBuffer, getQualifierBuffer, along the
right offset methods to the interface... Then I noticed that's exactly what you
did in the Cell interface. :)
There's one sticky issue still, where we use the key portion of the KV (i.e.
row, CF, qual), that would still need to be assembled on each call.
