>
> Statistics on data (data size, distribution etc) and performance (compute
> time/CPU time etc) are important in making runtime decisions on plan
> reconfiguration. For that it would be useful to have a uniform infrastructure
> that provides this information and make it available via an API so that user
> code in vertex managers etc can make use of this data to make decisions. This
> umbrella jira tracks improvements needed in Tez to support this.
