   > > Yes! The command will potentially read some key which doesn't exist in the cluster.
   > > Currently the freon command would stop running & report failure, but let me think more about this how to make it better!!
   > 
   > Code can continue testing and add a metric at the end for successful reads vs. not found read. It is a valid test to look at the performance of OM to report a key does not exist. Object Stores can be bombarded with nonexistent keys, and the performance of the underlying storage to report keys that don't exist is important. LSM tree-based storage has to scan all levels before reporting a key as not found and in some ways represents the worst case performance at scale.
   
   Thanks Ritesh for the context!! I'll create a separate jira regarding to this! This definitely make sense!!
