------------------------------------------

             Summary: Use Job Stages For Estimating Memory Requirement
                 Key: ASTERIXDB-2263
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-2263
             Project: Apache AsterixDB
          Issue Type: Improvement
            Reporter: Murtadha Hubail


Currently, we calculate a job's estimated memory usage based on all of its operators, which could lead to huge over estimation. It is better to use job stages to calculate better estimation.
