David Cai updated CARBONDATA-4062:
----------------------------------
Description:
To prevent accidental deletion of data, carbon will introduce data trash
management. It will provide buffer time for accidental deletion of data to roll
back the delete operation.
Data trash management is a part of carbon data lifecycle management. Clean
files as a data trash manager should contain the following two parts.
part 1: manage metadata-indexed data trash.
this data should be at the original place
part 2: manage ".Trash" folder.
Now this ".Trash" folder is without metadata index, and the operation on it
will depend on timestamp and listFile interface. It should be improve in the
future.
