Consistency of metrics and audience membership counts between Real-time CDP and CJA

In real-world scenarios, consistency of metrics and audience membership counts across Real-time Customer Data Platform (Real-time CDP) and Customer Journey Analytics (CJA) cannot be guaranteed. This document explains why.

When comparing audience membership counts between Real-time CDP and CJA, it is important to keep in mind the different purposes of these two tools. Real-time CDP uses customer profile data to target digital experiences to individual consumers, while CJA is designed to help users understand patterns in key business metrics and segments. While audience publishing from CJA to Real-time CDP allows a user of these tools to easily and natively “activate” an insight, taking advantage of learnings obtained in CJA, these tools nevertheless serve fundamentally different purposes.

Differences in identity configurations

Real-time CDP and CJA do not share the same definition of a person today. Real-time CDP relies entirely on the information in the Identity Graph to build a merged profile.

CJA can be configured to use Cross-Channel Analytics which extracts identifiers from datasets in the data lake and applies custom logic to link them together.

In the future, CJA will be able to use Identity Graph.

Differences in dataset configuration

You can choose to put some data in Real-time CDP and some in CJA; often, customers choose to put more historical data in CJA than is relevant for Real-time CDP. Other datasets might be more relevant for Real-time CDP than for CJA.

Differences in processing configuration

CJA allows for extensive data modification at query time, such as combining fields, splitting fields apart, and other manipulations like includes/excludes, substrings, value de-duplication, sessionization, and row-level filtering.

Real-time CDP offers a different set of data manipulation tools. It applies merge policies to determine which data will be prioritized and what data will be combined to create a unified view of a person.

Differences in TTL (Time to Live) and data ingestion

Even if the datasets in Real-time CDP and CJA are the same, Real-time CDP may only keep a very limited window of history. By contrast, CJA likely has years’ worth of data. In addition:

  • CJA and Real-time CDP customers can set custom retention windows for data, independent of each other.

  • Real-time CDP and CJA have different logic for ingesting data. CJA ignores records without a person ID or timestamp and has strict limits to the number of records a single profile/person may have.

  • Real-time CDP customers get 7 days of access to data in the lake, primarily to facilitate data onboarding into profile and for ad-hoc querying.

  • There are no TTLs for the data in the lake for CJA customers. CJA users however can themselves set a custom retention window in CJA when creating a connection.

  • Profile Store in Real-time CDP allows for customer-configurable TTLs. Customers can change this TTL to whatever they need to stay within their license entitlements.

Differences in data ingestion latency

CJa does not yet have the real-time capabilities of Real-time CDP and as a result, CJA reporting includes some latency before data is available for reporting or audience creation. Real-time CDP processes data through different systems that have different latency.
