Labels: pull-request-available (was: )
> Add prefix iterator support to RDBTable.
> ----------------------------------------

> Key: HDDS-6428
> URL: https://issues.apache.org/jira/browse/HDDS-6428
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Mark Gui
> Assignee: Mark Gui
> Priority: Major
> Labels: pull-request-available
>
> So after rocksdb-merge, in schema v3, we will have containerID as key
> prefixes for all keys in per-disk rocksdb instances.
> We should add support for iterating the keys with prefixes.
> h4. We can add a new field -- "prefix" -- in existing RDBStoreIterator.
> Then we check for the prefix field to decide how to iterate through all the
> keys:
> * if we have the prefix set, then we seek to the first key with the prefix
> before iteration and end iteration upon the first key doesn’t match the
> prefix.
> * else we keep the old way of iterating.
