Nanda kumar commented on HDDS-271:
----------------------------------
Do we have to use {{getRangeKVs}} and load all the values into memory for an
iterator implementation? We can take advantage of the db iterator that is
provided by RocksDB/LevelDB. We might be missing on richer APIs like
{{getBlockCount}}, but do we really need those APIs for an Iterator? Loading
all the values into a list for an iteration will have huge memory impact if we
create iterators for multiple containers at the same time.
