This may cause performance issues when reroute events are processed.\r\n\r\nThe possible solution is alternative views of the flow data: a map of node_id to flow_id, isl to flow_id, etc. Or re-implement the cache to use http://commons.apache.org/proper/commons-collections/javadocs/api-release/org/apache/commons/collections4/map/MultiKeyMap.html "}}
