About This Domain
Domain 1 — Designing Data Processing Systems — accounts for ~23% of the PDE certification exam. This domain evaluates your understanding of lambda vs kappa architecture, dataflow (apache beam) for unified batch/stream, pub/sub for real-time ingestion, and related concepts. Designing batch and streaming data pipelines. To pass this section you need practical knowledge of how these services and patterns work together in real-world architectures.
What You'll Be Tested On
- Lambda vs Kappa architecture
- Dataflow (Apache Beam) for unified batch/stream
- Pub/Sub for real-time ingestion
- BigQuery for analytics
