             Summary: Revise scan limit pushdown
                 Key: DRILL-8123
                 URL: https://issues.apache.org/jira/browse/DRILL-8123
             Project: Apache Drill
          Issue Type: New Feature
            Reporter: Paul Rogers
            Assignee: Paul Rogers


Recent work added a push down of the limit into a scan. The work had a few holes, one of which was plugged by the recent update of EVF to manage the limit. Another hole is that the physical plan uses a value of 0 to indicate no limit, but 0 is a perfectly valid limit, it means "no data, only schema." The field name is "maxRecords", but should be "limit" to indicate the purpose.
