Key Topics Covered

The Databricks Data Engineer Professional Exam covers a wide range of topics, so you'll want to make sure you're well-versed in each area. Here's a breakdown of the key areas you'll need to know:

Data Ingestion: This includes understanding how to ingest data from various sources, such as files, databases, and streaming data sources. You should be familiar with tools like Auto Loader, Delta Lake, and different file formats (e.g., CSV, JSON, Parquet). You'll also need to know how to handle schema evolution and data validation during ingestion. Think about how you'd load data from a variety of sources, deal with schema changes, and make sure everything is running smoothly.
Data Transformation: This is where you'll flex your Spark and SQL muscles. You'll need to be proficient in writing and optimizing data transformations using Spark DataFrames, SQL queries, and UDFs (User-Defined Functions). You'll also need to understand how to handle data cleaning, aggregation, and joining. Consider how you'd transform messy data into a clean, usable format, and how to optimize your queries for performance.
Data Storage: You'll need to understand how to store data in Delta Lake, the open-source storage layer that provides ACID transactions. This includes knowing how to create, manage, and optimize Delta tables, as well as how to handle data versioning and time travel. Think about how you would organize and manage your data for efficient querying and reliable access.
Data Pipeline Development: You'll need to know how to build and orchestrate data pipelines using tools like Databricks Workflows and Apache Airflow. This includes understanding how to schedule, monitor, and troubleshoot pipelines. Imagine how you'd build an automated data pipeline that handles everything from data ingestion to transformation and storage.
Data Governance and Security: This involves understanding how to secure your data and ensure data quality. You'll need to be familiar with access control, data masking, and data lineage. Consider how you'd protect sensitive data and make sure your data pipelines are compliant with privacy regulations.
Performance Optimization: You'll need to understand how to optimize your data pipelines for performance, including how to tune Spark configurations, optimize SQL queries, and leverage caching. Think about how you would speed up a slow-running data pipeline.

These are the main topics, but Databricks may add new topics to the exam. Stay updated.
