Databricks Data Engineer Professional Exam Syllabus Topics:

Topic Details Weights
Developing Code for Data Processing using Python and SQL - Using Python and Tools for development
  • Design and implement a scalable Python project structure optimized for Databricks Asset Bundles (DABs), enabling modular development, deployment automation, and CI/CD integration.
  • Manage and troubleshoot external third-party library installations and dependencies in Databricks, including PyPI packages, local wheels, and source archives.
  • Develop User-Defined Functions (UDFs) using Pandas/Python UDF.

- Building and Testing an ETL pipeline with Lakeflow Declarative Pipelines, SQL, and Apache Spark on the Databricks platform

  • Build and manage reliable, production-ready data pipelines, for batch and streaming data using Lakeflow Declarative Pipelines and Autoloader.
  • Create and Automate ETL workloads using Jobs via UI/APIs/CLI.
  • Explain the advantages and disadvantages of streaming tables compared to materialized views.
  • Use APPLY CHANGES APIs to simplify CDC in Lakeflow Declarative Pipelines.
  • Compare Spark Structured Streaming and Lakeflow Declarative Pipelines to determine the optimal approach for building scalable ETL pipelines.
  • Create a pipeline component that uses control flow operators (e.g. if/else, foreach, etc.)
  • Choose the appropriate configs for environments and dependencies, high memory for notebook tasks, and auto-optimization to disallow retries.
  • Develop unit and integration tests using assertDataFrameEqual, assertSchemaEqual, DataFrame.transform, and testing frameworks, to ensure code correctness, including a built-in debugger.

Cost & Performance Optimisation - Understand how / why using Unity Catalog managed tables reduces operation Overhead and maintenance burden.
- Understand delta optimization techniques, such as deletion vectors and liquid clustering.
- Understand the optimization techniques used by Databricks to ensure the performance of queries on large datasets (data skipping, file pruning, etc).
- Apply Change Data Feed (CDF) to address specific limitations of streaming tables and enhance latency.
- Use query profile to analyze the query and identify bottlenecks, such as bad data kipping, inefficient types of joins, data shuffling.		 13%
Ensuring Data Security and Compliance - Applying Data Security mechanisms.
  • Use ACLs to secure Workspace Objects, enforcing the principle of least privilege, including enforcing principles like least privilege, policy enforcement.
  • Use row filters and column masks to filter and mask sensitive table data.
  • Apply anonymization and pseudonymization methods such as Hashing, Tokenization, Suppression, and Generalization to confidential data.
