Hi, For BEAM-2774 <https://issues.apache.org/jira/browse/BEAM-2774>, I had proposed to create a new Variant proto as the type of the returned PCollection. I was originally planning to define it somewhere within Beam, but since then we've decided it may be better to define it in a more generic environment (e.g. under https://github.com/googlegenomics) or even reuse this one <https://github.com/googleapis/googleapis/blob/master/google/genomics/v1/variants.proto#L418> .
My questions are: - Is it ok to include an external proto inside a Beam IO source? Note that the repo will be owned by Google. - If so, what is the best way to do it? Does it have to be a pip package? Thanks, Asha
