             Summary: Support tables that can be relational and streamable?
                 Key: CALCITE-7513
                 URL: https://issues.apache.org/jira/browse/CALCITE-7513
             Project: Calcite
          Issue Type: New Feature
          Components: core
    Affects Versions: 1.41.0
            Reporter: Stephen Buergler


I don't know much about calcite yet so if there is a reason to not do this let me know.
Currently it looks like you can't make a Table implement ScannableTable and StreamableTable. It fails validation when you select from it because org.apache.calcite.prepare.RelOptTableImpl#supportsModality says the modality isn't supported. I think it would make more sense if that tested to see if the Table implements one of the selectable interfaces rather than the current 
{code:java}
!(table instanceof StreamableTable)
{code}
.
