Description

It would be better if fig/program_dataflow.svg used a ProcessWindowFunction, rather than a WindowFunction.

It also uses a BucketingSink, which sets a bad example. 

Note that this is not a trivial edit, since it doesn't work to simply replace new BucketingSink with new StreamingFileSink. Something like this would be better:

 
final StreamingFileSink<GenericRecord> sink = StreamingFileSink
        .forBulkFormat(...)
        .build();

stats.addSink(sink);

Note: This figure is only used once, in the Training Overview page.
