> Project: IMPALA
> Issue Type: Improvement
> Reporter: Qifan Chen
> Assignee: Qifan Chen
> Priority: Minor
> Fix For: Impala 4.0

>
> Currently per fragment, in addition to fragment instance profile, only an
> average profile is provided. One has to go over fragment instance profiles
> to figure out whether there exist skews. By skews we mean certain operator
> instances process much more rows than others for the same fragment.
> It will be useful if skew information can be provided in the run-time
> profile.
