Events Overview

Events Overview

An event is a representation of a publication or a subscription instance, at a particular stage of the publication or subscription process. The
Data Integration Hub
server generates events as it runs and processes publications and subscriptions, and it changes the status of the events as the publication or subscription process progresses. When an application triggers a publication, if the triggered publication has a pre-process, the publication event also tracks the pre-process. When a subscription triggers a post-process, the subscription event also tracks the post-process.
When an application that runs a publication pre-process publishes data or files to the publication repository, the
Data Integration Hub
server assigns an event to the publication as follows:
  • If the pre-process passes the Publication event ID to the publication process, the publication uses the same event, and the
    Data Integration Hub
    server does not generate an additional Publication event for the publication process.
  • If the pre-process does not pass the event ID to the publication process, the
    Data Integration Hub
    server generates another Publication event for the publication process.
If a file publication publishes more than one file,
Data Integration Hub
creates a File event for each file that it picks up.
Data Integration Hub
creates a Publication event after all the files are picked up.
The Publication event is the root event and the parent event for all of the subscription events that the
Data Integration Hub
server generates during the publication process. After the published data is ready for subscribers, the
Data Integration Hub
server generates a Subscription child event for each subscriber that needs to consume the published data. The Publication event contains aggregated status information for all Subscription child events.
An event changes status as it is processed. The
Data Integration Hub
server changes the status of an event based on a set of event statuses that you define in the Operation Console.
As each subscriber consumes the published data, the child event finishes processing. After all subscribers consume the published data, the
Data Integration Hub
server updates the consumption status of the parent event for the publication
.
You can manage storage space in the
Data Integration Hub
run-time repository by purging events that
Data Integration Hub
generates when they are no longer needed.
