Abstract: A method for failure event notification in an event recordation and distribution system. The method including monitoring each stage of processing of an event by an event publisher manager, detecting a failure of the event to publish in the event recordation and distribution system, and publishing an error event notification to a status stream in response to detecting the failure.

Abstract: A method of per subscription event filtering is provided for an event recordation and distribution system. The method includes receiving an event from the event recordation and distribution system, determining that an event consumer that is a subscriber of an event stream of the event has specified filter logic for the event stream, and forwarding the event to an event consumer in response to the event meeting requirements of the specified filter logic.

Abstract: A method and system for event consumers management are described. A batch of events that is stored in an event recordation system according to an aggregate topic is received based on the aggregate topic. Each event from the batch of events is associated with an initial topic to be used by a respective instance of an event consumer from a set of event consumers to consume events. A first initial topic associated with one or more events from the batch of events is determined. Based on the first initial topic, a state of a first event consumer is updated to a running state. The updated state of the first event consumer causes execution of a first instance of the first event consumer on a server of a cluster of servers for consuming events from the event recordation system based on the first initial topic.

Abstract: A method and system for event delivery are described. A batch of events for a first topic with replay identifiers is received. Responsive to determining that there is an active replay identifier discontinuity information for the first topic, a determination is performed of whether the first batch of events includes a second set of events that fills the discontinuity identified in the replay identifier discontinuity information. Upon determining that the first batch of events includes a second subset of events with second respective replay identifiers that start from the last replay identifier and do not include a discontinuity the second subset of events is transmitted to an event consumer, and the replay identifier discontinuity information for the first topic is updated based on the second subset of events transmitted.

Abstract: A method to convert data between a relational format and an XML document, by creating a set of XML Mapping Definition from metadata; selecting relational data from a relational application database, and converting the relational data to the XML document using the set of XML Mapping Definition.
