About the Big Data & Streaming certification
The Big Data & Streaming certification validates that you can design, reason about and operate real-time and large-scale data systems. You will move beyond batch thinking into the world of unbounded data, where records arrive continuously and correctness depends on when you process them, not just what you process. The exam covers the big-data 5 Vs, distributed storage (HDFS and object storage) and distributed-computing fundamentals; Apache Kafka in depth — topics, partitions, offsets, consumer groups, replication, retention, log compaction and exactly-once semantics; stream processing with Spark Structured Streaming and Apache Flink; event time vs processing time, windowing (tumbling, sliding, session), watermarks and late-data handling, stateful processing and checkpointing; delivery guarantees (at-most-once, at-least-once, exactly-once); the lambda and kappa architectures; change-data-capture streaming, backpressure, message queues vs event streams, the streaming lakehouse (Delta/Iceberg), real-time OLAP stores (Druid/ClickHouse), and the scalability, fault-tolerance and monitoring of streaming pipelines. It is engine-agnostic: the concepts transfer across Kafka, Flink, Spark, Pulsar and managed cloud equivalents. Candidates should already hold the Data Engineering Professional credential or have equivalent hands-on pipeline experience.
What you will learn
The official Big Data & Streaming study course covers:
- Big Data Foundations — The 5 Vs, distributed storage (HDFS and object storage) and the move-compute-to-data principle.
- Apache Kafka In Depth — Topics, partitions, offsets, consumer groups, replication, retention and log compaction.
- Stream Processing & Time — Spark vs Flink, event time vs processing time, windowing and watermarks for late data.
- State, Guarantees & Fault Tolerance — Stateful processing, checkpointing/recovery and delivery semantics (at-most/at-least/exactly-once).
- Architectures, Analytics & Operations — Lambda vs kappa, CDC, backpressure, the streaming lakehouse, real-time OLAP and monitoring.
