Abstract
A method is provided for efficient event notification in a computer system. The method includes processing messages as events at an event notification engine of a computer system maintaining a database of subscriptions of a plurality of subscribers, the subscriptions including first predicates stored in the database as first datums that are searchable. This includes receiving a message as an event including a second datum. The event is transformed into a query in a query language used to search the database, the second datum being transformed into a second predicate that is included in the query. The query is executed in the database to search the first datums for a first datum that matches the second predicate, and from the first datum, identifying a subscription that matches the event, the subscription being for a subscriber to which the event is routed.
