Yuan Gu updated HDDS-5332:
--------------------------
Description:
Table schema:
{code:java}
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.
[06/21] Renamed ReconContainerDBProvider to ReconDBProvider
[06/21] Expanded the scope of this issue by designing a service provider
interface for namespace summary, which wraps up all operations on the new
schema.
