Zusammenfassung:	Systems and methods for filtering and routing event notifications to subscribers are disclosed. In an example embodiment, events from a publisher may be received. Each of the events may be associated with a topic, and the topic may be compared with topics present in broker metadata cache, based on one of prefixes and a fast lookup technique using a hash-table. Further, it may be determined whether the topic associated the events is present in the broker metadata cache based on comparison. Based upon determining, matching nodes for the events may be retrieved. Further, the events may be routed based on routing tables and availability of the matching nodes. Based on the routing, the events may be forwarded to the subscribers.
