Description
The goal of the "Streaming" page (1) on the Calcite website is to define a SQL syntax for queries that can be applied on continuous data streams as well as static tables.
However, it does not reflect the current state of discussion and should be updated.
- Update the syntax to define tumbling and hopping windows as proposed on the dev mailing list (2).
- Relax the requirement of for a monotonic expression / attribute and allow for expressions which are slightly out-of-order but guarded by punctuations (or watermarks, ) as discussed on the dev mailing list (3).
