     [ https://issues.apache.org/jira/browse/NIFI-6973?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Shawn Weeks resolved NIFI-6973.
-------------------------------
    Resolution: Won't Fix

Issues is caused by Calcite doing the calculation in memory. Since there isn't really a work around to that there isn't anything NiFi can do.

> In the attached example I am attempting to use the row_number() over() function in calcite to generate a row id. It works fine for smaller files but uses all the ram and cpu allocated to NiFi with larger files.
