If the :func:`~pyflink.table.GroupWindowedTable.group_by` only
references a GroupWindow
alias, the streamed table will be processed by a single task,
i.e., with parallelism 1.
+ Example:
+ ::
+
+ >>>
tab.window(Tumble.over("10.minutes").on("rowtime").alias("w")).group_by("w") \\
+ ... .select("a.sum as a, w.start as b, w.end as c, w.rowtime
as d")
Review comment:
What about putting the `group_by` statement in a separate line?
