Bikas Saha created TEZ-1167:
-------------------------------

             Summary: Statistics infrastructure and API for Tez
                 Key: TEZ-1167
                 URL: https://issues.apache.org/jira/browse/TEZ-1167
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Bikas Saha


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.
