---------------------------------------
Assignee: (was: Aravindan Vijayan)
> Ozone RocksDB Iterator wrapper should not expose key() and value() API.
> -----------------------------------------------------------------------
>
> Key: HDDS-3983
> URL: https://issues.apache.org/jira/browse/HDDS-3983
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Affects Versions: 0.6.0
> Reporter: Aravindan Vijayan
> Priority: Major
>
> While investigating HDDS-3965 with [~nanda619], it was found that there is
> discrepancy in the implementation of the next(), key() and value() methods in
> the RDBStoreIterator wrapper class.
> next() works by returning the current rocksdb entry and moves ahead to the
> next entry.
> key() returns current rocksdb entry's key.
> value() returns current rocksdb entry's value.
> This means that during iteration next() returns the current value, and
> subsequent calls to key() / value() after next() will return the next value.
> To solve this, we can remove those 2 APIs from the iterator class, and have
> the usages follow this pattern.
> {code}
> Iterator iter = rdbTable.iterator();
> while (iter.haxNext()) {
> Entry<Key,Value> entry = iter.next();
> // Use only entry.getKey(), entry.getValue().
> }
> {code}
