The API has changed since the issue was filed. Now we agreed upon the following: we just need to add {{RowId}} to {{{}ReadResult{}}}, so {{ReadResult}} will now have a method with the following signature:

{{RowId rowId();}}

> Row id is returned only for insert operation, but if you want to find a row id by Binary row is not possible.
> I sure, it has to be possible through scan operation. In that case, the scan operation can be used as a scan index.
> I would like to see API like:
> {code:java}
> Cursor<Tuple<RowId, BinaryRow>> scan(Predicate<BinaryRow> keyFilter, UUID txId) throws TxIdMismatchException, StorageException;
> Cursor<Tuple<RowId, BinaryRow>> scan(Predicate<BinaryRow> keyFilter, Timestamp timestamp) throws StorageException;
> {code}
