    Description

      Refactor the BySeq API to offer a `Status::GetValue(Slice& value)` API (just like ByKey) so that kv-engine can fetch the value only if they require it. This avoids lookups into keyIndex during DCP seq scan if the value separation hasn't happend.

      I have a patch in progress for this.
