--------------------------------------------------
[~julianhyde], I tried your fix with stream-to-relaiton join test. It works
now. Thanks for the fix.

> Stream joins are used to relate information from different streams or stream
> and relation combinations. Calcite lacks (proper) support for
> stream-to-relation joins and stream-to-stream joins.
> stream-to-relation join like below fails at the SQL validation stage.
> select stream orders.orderId, orders.productId, products.name from orders
> join products on orders.productId = products.id
> But if 'products' is a stream, the query is valid according to Calcite, even
> though the stream-to-stream join in above query is not valid due to unbounded
> nature of streams.
