Column lineage graph endpoint returns by defualt only inEdges which correspond to upstream lineage.
We do want to allow users to fetch outEdges (downstream lineage) with an extra URL parameter &withDownstream=true.
When so, inEdges and outEdges will be returned.
This can blur the graph overall, that's why we decided to allow this feature on demand.
See proposal for more details:
