Review Comment:
I think you can just use
[TableIterator#seekToFirst()](https://github.com/apache/ozone/blob/4b9b10f6206ed5c29c0c4957a651de1d24fe86f6/hadoop-hdds/framework/src/main/java/org/apache/hadoop/hdds/utils/db/RDBStoreAbstractIterator.java#L117),
if you wanna get all keys starts with prefix.
