Subject [jira] [Commented] (DRILL-3517) Add a UDF development FAQ
Date Tue, 21 Jul 2015 00:03:04 GMT

    [ https://issues.apache.org/jira/browse/DRILL-3517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14634309#comment-14634309
] 

Ted Dunning commented on DRILL-3517:
------------------------------------


8) My UDF is not a pure function so calling it with the same arguments will result in different
values each time.  Drill is only using the result of calling my function once.  How can I
fix that?
