Siyao Meng updated HDDS-5332:
-----------------------------
Description:
Table schema:
{code}
objectId --> class NSSummary
{code}
New class NSSummary should at least include these fields:
1. Total number of files *directly*[1] under this directory,
2. Total size of files directly under this directory,
3. File Size Buckets of files directly under this directory.
Note: [1] *directly* means not counting files under any subdirectories, for
now. We could further optimize the speed later by trading more writes
(propagating the statistics any layers deep upwards) with speed.

Need a new DBProvider for this.
