> VerifyReplicaiton could compare the source table with its peer table and
> compute BADROWS. However, the current BADROWS computing method might not be
> accurate enough. For example, if source table contains rows as {r1, r2, r3,
> r4} and peer table contains rows as {r1, r3, r4} BADROWS will be 3 because
> 'r2' in source table will make all the later row comparisons fail. Will it be
> better if the BADROWS is computed to 1 in this situation? Maybe, we can
> compute the BADROWS more accurately in merge comparison?
