> As Kudu supports predicates push down, bytes size of rows returned to the kudu client may differs a lot with the bytes size read from disk in tablet server side when running a scan. In some cases, the client side may need to know the actual resource usage. For example, impala may need this so it can estimate a query's actual resource usage.
