    data_events_topic->>data_events_consumer: Consumes event for new data (or other) event
    Note over data_events_topic,data_events_consumer: Consumes from Relation events Topics

    data_events_consumer->>our_hub_db: Store event in the DB

    our_hub_processor->>our_hub_db: Waits X minutes and then selects any un-sent datas
    our_hub_processor->>cdp_api: Potentially makes a call to gather more information about the data / user
    Note over our_hub_processor,cdp_api: TBC how this works in practice

    our_hub_processor->>our_gate: Creates the data notification(s) in our system
    our_gate->>our_api: Adds the notification(s) to the our system
