[jira] [Created] (IOTDB-4898) Push offset and limit down to ScanOperator if possible

Yuan Tian created IOTDB-4898:
--------------------------------

             Summary: Push offset and limit down to ScanOperator if possible
                 Key: IOTDB-4898
                 URL: https://issues.apache.org/jira/browse/IOTDB-4898
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Yuan Tian
            Assignee: Minghui Liu


Currently, we locate offset and limit at the root of the operator tree which will cause time cost increasing with offset even if limit is the same.

So, we need to push offset and limit down to ScanOperator if possible, and let ScanOperator use statistics to skip the offset
