USING DIFFERENT EVENT-DISTRIBUTION POLICIES TO STREAM EVENT DATA TO DIFFERENT EVENT CONSUMERS

Some embodiments provide a novel policy-driven method for providing event data to several event consumers. An event server stores in a set of one or more data storages event data published by a set of one or more event data publishers. The event server receives first and second different event-distribution policies from first and second event consumers for first and second streams of event data tuples for which the first and second event consumers register with the event server to receive. Each event consumer has multiple consumer instances. The event server uses the first and second event-distribution policies to differently distribute the first and second streams of event data tuples to the consumer instances of the first and second event consumers.
