> We do index writes as full row writes. This means all columns keep get
> re-written to index and they have a current timestamp.
> However, if there is a column that did not get updated for a long time (like
> Created_By type of columns that don't change) index inline validation marks
> these as "Index has extra columns". We need to publish an extra metric to
> distinguish these cases since they are expected to be not matching rows.
