Hi, Akash R:
  thanks for your reply.
  I am talking about the delta data files including update and delete delta
files. Horizontal compaction just compacts all delta files into one in one
segment, right? But if the size of segment is big and the size of update and
delete delta file is big too, I think it will effect the query performance,
because it needs to filter carbondata files and delta file, right?
