Hi [~rakeshr], I take the quick look for the first PR PR-1230. It reuses the
PrefixTable to store like directory info I have a question: this will not break
original key lookup behavior? We don't have the object id assigned for keys in
prefix table, but current logic assumes that each entry key has its own
objectId in table. Or maybe we will have a step to generate this object id
firstly when users start to enable this feature from their existed Ozone system.
