However, we would need to update the API more than just this -- right now TableFunctions have no way of getting inputs (they return TableProviders) We would have to work out what the API would look like if they got an input (perhaps they get an input ExecutonPlan) As you mention, we would also probably have to figure out planning for LATERALs, etc -- This is an automated message from the Apache Git Service.
