Hi everyone, The PR linked in [BEAM-3759] - "Add support for PaneInfo descriptor in Python SDK"[1] was merged, but, the issue is still open. There might be some work left on this for full support for PaneInfo. Eg: Although the PaneInfo class exists, it is not accessible in a DoFn via a kwarg(PaneInfoParam) like TimestampParam or WindowParam.
Please let me know the remaining work to be done on this issue as this may be needed in the near future. Regards Tanay Tummalapalli [1] https://issues.apache.org/jira/browse/BEAM-3759
