Ethan Rose commented on HDDS-12209:
-----------------------------------
I don't think we need to consider sorting the output in this initial
implementation, but we may want to consider supporting it optionally later with
a {{--sorted}} flag. Although keys' replicas would be verified in parallel, the
driver could wait for them to complete sequentially, only flushing the json
produced by one key's checks once its previous keys have completed. In most
cases this should not make a large difference, but if there is a slow key to
check it could back up the processing of other keys until it completes.

> Make {{ozone debug replicas verify}} use multiple threads to iterate keys and

> the output sequentially.
