Usage

omni_cloudevents: CloudEvents support

The omni_cloudevents extension enables creation, validation, and publication of standardized CloudEvents from SQL. It is a templated extension.

Setup

SELECT omni_cloudevents.instantiate(schema => 'omni_cloudevents');
SET search_path TO omni_cloudevents, public;

Creating Events

SELECT cloudevent(
    id     => gen_random_uuid(),
    source => 'https://service.com/endpoint',
    type   => 'user.login'
);

Optional parameters: datacontenttype, dataschema, subject, ts (defaults to now), data (any PG type), specversion (default 1.0).

Publishing Events

SELECT publish(
    cloudevent(
        id     => gen_random_uuid(),
        source => 'https://api.yourservice.com/sys',
        type   => 'file.uploaded',
        data   => 'data-lake-bucket-123'::text
    )
);

Published events are persisted in the cloudevents_egress table.

NOTICE Publisher

-- To observe uncommitted events:
SELECT omni_cloudevents.create_notice_publisher(publish_uncommitted => true);
-- Delete a publisher:
SELECT omni_cloudevents.delete_publisher(name);

Events generate JSON-formatted NOTICE messages with full event details.
