      Description

      This issue was brought up in Drill community: (https://issues.apache.org/jira/browse/DRILL-3597)

      For convenience, I copied and pasted the reporter Khurram Faraaz's description here:

      "The SQL standard defines a RESPECT NULLS or IGNORE NULLS option for lead, lag, first_value, and last_value window functions."

      In Calcite, we should have been able to recognized this option.
