> The Python SDK's FilebasedSink does not support windowed filenames. Currently the only filename template available is based on shards.
> The Java SDK has this feature in the `FilenamePolicy.windowedFilename()`. The python SDk only has a somewhat more simple implementation using a text template and `FileBasedSink._template_to_format()` which does not support windows.
