          Add basic support for streaming queries. This includes the STREAM keyword (e.g.

            Fixed in http://git-wip-us.apache.org/repos/asf/incubator-calcite/commit/0ecd8702.

            Includes the new STREAM keyword, support for project, filter, aggregate and sort streaming queries (join and windowed aggregate are not yet supported), support for monotonic expressions, and FLOOR/CEIL(datetime TO timeUnit) functions.

            See https://github.com/apache/incubator-calcite/blob/master/doc/STREAM.md for a description of streaming capabilities.
