> 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.
