Siyao Meng commented on HDDS-10298:
-----------------------------------
Thanks [~pratyush.bhatt] for reporting this.
If the RocksDB estimated column family row count API can be this wildly
inaccurate (and in turn, misleading), I think I would change it to hide the
total open key count by default. But add an option to return the accurate
counts (which has to iterate the whole table. slow) of OpenKeyTable and
OpenFileTable.
