Eugene Kirpichov commented on BEAM-3070:
----------------------------------------
Thanks! However, I strongly recommend to wait until
https://github.com/apache/beam/pull/3817 lands, and recommend to mimic the
(simpler and more general) design of that instead.
> Add support for windowed filenames in Python SDK

> Key: BEAM-3070
> URL: https://issues.apache.org/jira/browse/BEAM-3070
> Project: Beam
> Issue Type: Improvement

>
> 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.
