> A trait to determine if TableSources belong to the same remote execution engine. This could be part of TableSource or a separate optional trait next to it. I wonder if [`TableSource::as_any`](https://docs.rs/datafusion/latest/datafusion/logical_expr/trait.TableSource.html#tymethod.as_any) would be sufficient > The FederationOptimizer that hands-off plan chunks to the respective remote execution Optimizers. I am not sure how much benefit this would have over just a normal optimizer pass (I probably don't fully understand the proposal -- maybe some code would help explain it in more detail if you would like more specific feedback) > Some in-ecosystem federation plugins/examples such Flight SQL or ADBC. An example that shows how to replace some part of the plan with a FlightSQL or ADBC implementation would be awesome. -- This is an automated message from the Apache Git Service.
