> Key: IMPALA-13902
> URL: https://issues.apache.org/jira/browse/IMPALA-13902
> Project: IMPALA
> Issue Type: Sub-task
> Reporter: Steve Carlin
> Priority: Major
>
> In AnalysisContext, there is a method "returnsAtMostOneRow" on the SelectStmt
> that is used for result spooling.
> This is inaccessible in its current state by the Calcite planner since it is
> on StatementBase. The code should be refactored to handle this.
