Every input in Streamx is associated with an entry-point. Consider:

rule "First contact"
	when $currentFlight : FlightStatus() from entry-point "flight-control"

By using the from entry-point keyword, we specify that FligtStatus fact comes from “flight-control” entry point (input).

Note, that facts used for Amazon Kinesis data must be annotated with @role(event). While facts used for DynamoDB data must not. See fact roles.
