My events are firewall events with src, dest, and actions fields, and a firewall log event with allowed action is the connection between two nodes. My events: A -> target (raw event: src=A dest=target action=allow) B -> A (raw event: src=B dest=A action=allow) C -> B (raw event: src=C dest=B action=allow) D -> B (raw event: src=D dest=B action=allow) A -> C (raw event: src=A dest=C action=allow) C -> D (raw event: src=C dest=D action=allow) My goal is to find A, B, C, D nodes (all nodes that have a route/connection to the target node) with a recursive query.
