| Description |
|
In the current design: All files under a root WBC directory are allocated with FIDs located on the same target (MDT). And also in current implementation, it does not support default LMV on the root WBC directory. The above design can simply the batched metadata update and recovery (no any dependency) TODO: In the future, files under a root WBC directory could be distributed across MDT targets other than the one which the root WBC directory located on. This could increase concurrency for metadata performance. |
