Streaming segmentation

Streaming segmentation on Adobe Experience Platform allows customers to do segmentation in near real-time while focusing on data richness. With streaming segmentation, segment qualification now happens as streaming data lands into Platform, alleviating the need to schedule and run segmentation jobs. With this capability, most segment rules can now be evaluated as the data is passed into Platform, meaning segment membership will be kept up-to-date without running scheduled segmentation jobs.

Streaming segmentation query types query-types

A query will be automatically evaluated with streaming segmentation if it meets any of the following criteria:

Query type

Details

Example

Single event

Any segment definition that refers to a single incoming event with no time restriction.

Single event within a relative time window

Any segment definition that refers to a single incoming event.

Single event with a time window

Any segment definition that refers to a single incoming event with a time window.

Profile only

Any segment definition that refers to only a profile attribute.

Single event with a profile attribute within a relative time window of less than 24 hours

Any segment definition that refers to a single incoming event, with one or more profile attributes, and occurs within a relative time window of less than 24 hours.

Segment of segments

Any segment definition that contains one or more batch or streaming segments. Note: If a segment of segments is used, profile disqualification will happen every 24 hours.

Multiple events with a profile attribute

Any segment definition that refers to multiple events within the last 24 hours and (optionally) has one or more profile attributes.

A segment definition will not be enabled for streaming segmentation in the following scenarios:

Please note the following guidelines apply when doing streaming segmentation:

If a segment definition is modified so it no longer meets the criteria for streaming segmentation, the segment definition will automatically switch from “Streaming” to “Batch”.

Additionally, segment unqualification, similarly to segment qualification, happens in real-time. As a result, if an audience no longer qualifies for a segment, it will be immediately unqualified. For example, if the segment definition asks for “All users who bought red shoes in the last three hours”, after three hours, all the profiles that initially qualified for the segment definition will be unqualified.

Streaming segmentation segment definition details

After creating a streaming-enabled segment, you can view details of that segment.

Specifically, the Total qualified metric is displayed, which shows the total number of qualified audiences, based on batch and streaming evaluations for this segment.

Underneath is a line graph that shows the number of new audiences that were updated in the last 24 hours using the streaming evaluation method. The dropdown can be adjusted to show the last 24 hours, last week, or last 30 days. The New audience updated metric is based on the change in audience size during the selected time range, as evaluated by streaming segmentation. This metric does not include the total qualified audience from the daily segment batch evaluation.

Additional information about the last segment evaluation can be found by selecting the information bubble next to Total qualified.

Appendix

The following section lists frequently asked questions regarding streaming segmentation:

Does streaming segmentation “unqualification” also happen in real time?

For most instances, streaming segmentation unqualification happens in real-time. However, streaming segments that use segments of segments do not unqualify in real-time, instead unqualifying after 24 hours.

What data does streaming segmentation work on?

Streaming segmentation works on all data that was ingested using a streaming source. Segments ingested using a batch-based source will be evaluated nightly, even if it qualifies for streaming segmentation. Events streamed into the system with a timestamp older than 24 hours will be processed in the subsequent batch job.

How are segments defined as batch or streaming segmentation?

A segment definition is defined as batch, streaming, or edge segmentation based on a combination of query type and event history duration. A list of which segments will be evaluated as a streaming segment definition can be found in the streaming segmentation query types section.

Please note that if a segment definition contains both an inSegment expression and a direct single-event chain, it cannot qualify for streaming segmentation. If you want to have this segment definition qualify for streaming segmentation, you should make the direct single-event chain its own segment.

Why does the number of “total qualified” segments keep increasing while the number under “Last X days” remains at zero within the segment definition details section?

The number of total qualified segments is drawn from the daily segmentation job, which includes audiences that qualify for both batch and streaming segments. This value is shown for both batch and streaming segments.

The number under the “Last X days” only includes audiences that are qualified in streaming segmentation, and only increases if you have streamed data into the system and it counts toward that streaming definition. This value is only shown for streaming segments. As a result, this value may display as 0 for batch segments.

As a result, if you see that the number under “Last X days” is zero, and the line graph is also reporting zero, you have not streamed any profiles into the system that would qualify for that segment.

How long does it take for a segment definition to be available?

It takes up to one hour for a segment definition to be available.
