             Summary: Add timing metric for how long the query spent in scan
                 Key: SPARK-14210
                 URL: https://issues.apache.org/jira/browse/SPARK-14210
             Project: Spark
          Issue Type: Improvement
            Reporter: Nong Li
            Priority: Minor


With inputs that return batches, we can now measure how long it took to scan the data vs the rest of the processing. This is helpful to reason about the performance.
