Mh, I just realized that the streaming APIs multichaining is leading to
some ugly side effects.
In below screenshot, you see that the number of outgoing records is
reported as 247. These records are the number of elements emitted by the filter.
The task below the source is the window that is consuming the data from the
filter.
Now the next two tasks also consume data from the same task, but without
the filter. You can see that they've consumed much more data (because its
unfiltered).
