Fang Yong commented on FLINK-31275:
-----------------------------------
[~mobuchowski] Sorry for the late reply.
What does the `DataSet` in `LineageVertex` use for? Why a `LineageVertex` have
multiple inputs or outputs? We hope that 'LineageVertex' describes a single
source or sink, rather than multiple. So I prefer to add `Map<String, Facet>`
to `LineageVertex` directly to describe the particular information. We
introduce `LineageEdge` in this FLIP to describe the relation between sources
and sinks instead of add `input` or `output` in `LineageVertex`.
