["Andrew Pilloud (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEAM-9698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17107791#comment-17107791 ] 

Andrew Pilloud commented on BEAM-9698:
--------------------------------------

Looks like this is coming out of BeamZetaSqlCalcRel...

    BeamZetaSqlCalcRel(expr#0=[{inputs}], $unnest1=[$t0])
      BeamUncollectRel
        BeamZetaSqlCalcRel(expr#0=[{inputs}], expr#1=[null:BIGINT NOT NULL ARRAY], $array$unnest1=[$t1])
          BeamValuesRel(tuples=[[{ 0 }]])
