> Commit of RW transaction is not instantaneous. RO transaction might require reads of data that's in the process of being committed. Current API doesn't support such scenario.
> RO API in partition storage has only two methods: read and scan.
> For read see https://issues.apache.org/jira/browse/IGNITE-17627
> h3. Scan
> This one is tricky, we can't just return a cursor. Special type of cursor is required, and it must allow same read capabilities on each individual element.
> API is to be defined.
