Event subscriptions are obtained for a given event consumer. The event subscriptions define the events to be routed to this event consumer. Pre-filters of varying complexity and filtering power are constructed based on these event subscriptions. A balance between pre-filter efficiency and pre-filter throughput may be achieved by selecting the best pre-filter out of these constructed pre-filters to filter events to its associated event consumer. The best pre-filter is selected by comparing a complexity threshold (e.g., a limit for the number of atomic Boolean expressions in a pre-filter) with the actual complexity (e.g., the actual number of atomic Boolean expressions) for each constructed pre-filter and selecting the most complex pre-filter without exceeding the threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Generation of a set of pre-filters from a set of event subscriptions to more efficiently select events of interest","description":"A method, system and computer program product for achieving a balance between pre-filter efficiency and pre-filter throughput.
