Sergey Shelukhin commented on HBASE-7413:
-----------------------------------------
After some consideration, KVs might not just be written into a byte buffer, but
actually interleaved with protobuf records. Each such KV block could have
several KVs, and the protobuf structure is going to have corresponding number
of "WALEdit" records that don't have KVs but have, for example, KVs.
WALEdit inside protobuf as a byte buffer will result in unnecessary copies on
the write path.
