> In the current implementation, the index read repair deletes only the cells
> that are returned by the scan initiated by the Phoenix client instead of
> deleting all the cells of an invalid unverified row.
> The read repair deletes cells (i.e., a specific version of a row) only when
> if an index row is overwritten but the corresponding data table row overwrite
> fails. This leaves the the index row in the unverified status. Then the read
> repair detects this unverified row when it is scanned and needs to delete the
> cells of this unverified version of the row. However, the read repair (i.e.,
> GlobalIndexChecker) puts the delete markers for only the cells returned by
> the scan. If the scan does not return all the cells of the row, then only a
> subset of the cells of the row will be deleted. The remaining cells will not
> be removed and can be returned by the scans initiated later.
