   # [DRILL-8123](https://issues.apache.org/jira/browse/DRILL-8123): Revise 
scan limit pushdown
   
   ## Description
   
   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.
   
   ## Documentation
   
   N/A
   
   ## Testing
   
   Reran unit tests.
