Bharat Viswanadham commented on HDDS-936:
-----------------------------------------
I think we can have a server in OM end, that listens to client requests for
mapping between the key to containers and blocks, and container to ozone
objects and blocks.
1. First Part get the key to Container and block Info, can get easily by
reading the keyTable (as this server is on OM end, we don't need a copy of the
DB to another location)
2. For this we need to have read entire DB, then only we can provide the
information which is not feasible for every CLI request, we can make use of
rocksdb snapshots here and read the data every configured interval and update
our data structures.
