Azure Event Hubs connection

Overview overview

Azure Event Hubs is a big data streaming platform and event ingestion service. It can receive and process millions of events per second. Data sent to an event hub can be transformed and stored by using any real-time analytics provider or batching/storage adapters.

You can create a real-time outbound connection to your Azure Event Hubs storage to stream data from �۶���Ƶ Experience Platform.

Use Cases use-cases

By using streaming destinations such as Azure Event Hubs, you can easily feed high-value segmentation events and associated profile attributes into your systems of choice.

For example, a prospect downloaded a white-paper which qualifies them into a “high-propensity to convert” segment. By mapping the audience that the prospect falls in to the Azure Event Hubs destination, you would receive this event in Azure Event Hubs. There, you can employ a do-it-yourself approach and describe business logic on top of the event, as you think would work best with your enterprise IT systems.

Supported audiences supported-audiences

This section describes which types of audiences you can export to this destination.

Profile export behavior profile-export-behavior

Experience Platform optimizes the profile export behavior to your Azure Event Hubs destination, to only export data to your destination when relevant updates to a profile have occurred following audience qualification or other significant events. Profiles are exported to your destination in the following situations:

In all the cases described above, only the profiles where relevant updates have occurred are exported to your destination. For example, if an audience mapped to the destination flow has a hundred members, and five new profiles qualify for the segment, the export to your destination is incremental and only includes the five new profiles.

Note that the all the mapped attributes are exported for a profile, no matter where the changes lie. So, in the example above all the mapped attributes for those five new profiles will be exported even if the attributes themselves haven’t changed.

What determines a data export and what is included in the export what-determines-export-what-is-included

Regarding the data that is exported for a given profile, it is important to understand the two different concepts of what determines a data export to your Azure Event Hubs destination and which data is included in the export.

For example, consider this dataflow to an Azure Event Hubs destination where three audiences are selected in the dataflow, and four attributes are mapped to the destination.

A profile export to the destination can be determined by a profile qualifying for or exiting one of the three mapped segments. However, in the data export, in the segmentMembership object (see Exported Data section below), other unmapped audiences might appear, if that particular profile is a member of them and if these share the same merge policy as the audience that triggered the export. If a profile qualifies for the Customer with DeLorean Cars audience but is also a member of the Watched “Back to the Future” movie and Science fiction fans segments, then these other two audiences will also be present in the segmentMembership object of the data export, even though these are not mapped in the dataflow, if these share the same merge policy with the Customer with DeLorean Cars segment.

From a profile attributes point of view, any changes to the four attributes mapped above will determine a destination export and any of the four mapped attributes present on the profile will be present in the data export.

Historical data backfill historical-data-backfill

When you add a new audience to an existing destination, or when you create a new destination and map audiences to it, Experience Platform exports historical audience qualification data to the destination. Profiles which qualified for the audience before the audience was added to the destination are exported to the destination within approximately one hour.

Exported data exported-data

Your exported Experience Platform data lands in your Azure Event Hubs destination in JSON format. For example, the export below contains a profile that has qualified for a certain segment, is a member of another two segments, and exited another segment. The export also includes the profile attribute first name, last name, date of birth, and personal email address. The identities for this profile are ECID and email.

{
  "person": {
    "birthDate": "YYYY-MM-DD",
    "name": {
      "firstName": "John",
      "lastName": "Doe"

Limits and retry policy limits-retry-policy

In 95 percent of the time, Experience Platform attempts to offer a throughput latency of less than 10 minutes for successfully sent messages with a rate of less than 10 thousand requests per second for each dataflow to an HTTP destination.

In case of failed requests to your HTTP API destination, Experience Platform stores the failed requests and retries twice to send the requests to your endpoint.
