A composable CDP and a Customer Data Lake serve different purposes:

• Composable CDP: Modular platform focused on real-time data activation, audience building, and customer engagement with structured, processed data optimized for immediate use
• Customer Data Lake: Centralized storage repository for raw, unstructured data used for advanced analytics, data science, and long-term retention

While both store customer data, a composable CDP is better suited for real-time customer engagement, while data lakes excel at comprehensive analytics and data science workflows.
