> Currently structured streaming supports two kinds of windows: tumbling window and sliding window. Another useful window function is session window. Which is not supported by SS. We have user requirement to use session window. We'd like to have this support in the upstream.
> About session window, there is some info: https://ci.apache.org/projects/flink/flink-docs-stable/dev/stream/operators/windows.html#session-windows.
