-------------------------------------
h3. Dev Design
- During segment merge, add a check: If the segment is empty, do not use
`source_bytes_size` to calculate `column_source_bytes`.
- When retrieving `column_source_bytes` for a segment, check if it is an empty
segment. If it is empty, return an empty map.
> Incorrect Segment Size Calculation When Data Source Format is ORC and Data is
> Empty
