Examples

multihop - Simple as possible demonstration of a graph with two partitions alpha and beta, where beta depends on alpha.

Ideas

Search to detail page behavior to conversion to return pipeline
Add in "profile resolution" step to capture dep type? (e.g. person signs in at checkout)
"input" partitioning: date, country (different infra/laws/products/culture), customer? (what if its for shopify)
search ranking modeling flow: TDC, train, inference (simple linear model)
cross-customer product fraud alliance to qualify products (excuse to have fan-in-and-out pattern - "opt in")
sessionizing/preprocessing impressions
returns happen later, and handling them in an atomic, final way
performance metrics aggregates
what does multiple paths back to the same partition?
