------------------------------------------------
Summary: Support stream joins
Key: CALCITE-968
URL: https://issues.apache.org/jira/browse/CALCITE-968
Project: Calcite
Issue Type: New Feature
Components: core, stream
Reporter: Milinda Lakmal Pathirage
Assignee: Julian Hyde
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.
