> In the new index design, an index row is composed of cells with the same
> timestamp and the empty column cell holds the verify status of the row.
> However, it is possible that the empty column of an index row can be
> compacted away if the row is made unverified due to a failed data table
> overwrite. This failed overwrite will make the existing verified row index
> row unverified by overwriting the existing row with the empty column cell
> with the unverified status. If this row is not scanned before the next major
> compaction, the empty column cell of the overwritten index row can be removed
> by the compaction since there will be more than one version of it. If this
> row is retrieved via an SCN connection, then the returned row will not
> include the empty column cell. Not having empty column is treated as an
> exception currently. Instead, the row without an empty column should be
> treated as an unverified row and it should be repaired.
