CDESS study guide

CDESS · Work through your exam, one topic at a time.

The CDESS designation refers to the Cloudera Data Engineering Specialty credential, one of the specialty certifications Cloudera lists under its certification program. Cloudera's own certification page describes the program as part of its training and support offerings, and the vendor's product navigation places Data Engineering within the Open Data Lakehouse product family alongside Apache Iceberg, Data Warehouse, and Operational Database, with Data in Motion covering Data Flow, Streaming, and Edge Management, and Shared Data Experience covering the Data Catalog. The CDESS study guide has 4 sections and about 1,563 words.

Data Engineering: CDE Jobs, Virtual Clusters, and Orchestration

The Data Engineering domain tests whether you can define, schedule, and operate Spark workloads on Cloudera Data Engineering (CDE), the CDP service that runs jobs on Kubernetes virtual clusters rather than on static YARN queues. Expect questions on job types, resources, dependencies, run lifecycle, and how CDE sizing interacts with Spark configuration.

Data in Motion / Streaming: Kafka, Schema Registry, and NiFi

This domain covers ingestion and event transport in CDP: Apache Kafka for durable logs, Streams Messaging Manager (SMM) and Schema Registry for operations and contracts, Streams Replication Manager (SRM) for cross-cluster replication, and Apache NiFi (Cloudera Flow Management) for flow-based ingestion. Ordering is guaranteed only within a partition.

Open Data Lakehouse and Apache Iceberg: Format, Evolution, and Maintenance

This domain tests the table format that lets Spark, Impala, Flink, and Trino share one copy of data on object storage with ACID behavior, schema evolution, and time travel. An Iceberg table is a metadata file pointing to a snapshot.

CDP Administration and Security: Cloudera Manager, SDX, and Identity

This domain tests how a CDP deployment is managed and how access is governed: Cloudera Manager for service lifecycle, the Shared Data Experience (SDX) for security and governance, and the identity plumbing connecting them. Cloudera Manager deploys parcels, manages hosts and roles, and applies Data Hub templates.
