hi Linwood,
  1. better to implement "Update feature enhancement" at first, it will
create a new segment to store new files.
http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/Discussion-Update-feature-enhancement-td99769.html
  2. clean deletedelta files
      now carbon need clean invalid .deletedelta files before update/delete.
If we don't clean them, after next update/delete, these files will become
valid .deletedela files.

      How to avoid clean invalid .deletedelta files and they don't impact
data after next update/delete operation?
