It should also be smart enough to handle an order like:
source("bro")
-> parser("BasicBroParser")
-> exists("ip_src_addr")
-> geo_ip_src = geo["ip_src_addr"]
-> application = assets["ip_src_addr"].application
-> owner = assets["ip_src_addr"].owner
-> exists("ip_dst_addr")
-> geo_ip_dst = geo["ip_dst_addr"]
-> elasticsearch("bro-index")
Without duplicate hits of the topologies.
