~1 month~1 month
Step 0 - Data engineering foundations
Build the programming and data fundamentals that every data engineering task depends on. This is the foundation that makes Fabric-specific skills learnable.
- Python programming: functions, classes, pandas, PySpark basics, virtual environments
- SQL fluency: SELECT, JOIN, GROUP BY, window functions, CTEs, MERGE for upserts

- Data engineering concepts: batch vs streaming, ETL vs ELT, medallion architecture
- Git fundamentals: version control for data engineering projects, branching strategies
💡 KQL is genuinely new for engineers coming from SQL-only backgrounds. Fabric's Real-Time Intelligence uses KQL as its primary language. This is not optional.
💡 Delta Lake is central to Fabric. Understanding ACID transactions, time travel, and schema evolution is foundational.
🏁 Entry Level Checkpoint 1: You can write Python, SQL, and basic KQL queries. You understand data formats.
🛠 Project Ideas
- ▸Write a Python script that reads a CSV, transforms it with pandas, and writes it to Parquet format.
- ▸Write a SQL query that joins three tables and uses a window function for ranking.
- ▸Write a KQL query that filters events and summarizes counts by category.
Step 1 - Data fundamentals and platform orientation (DP-900)
Build familiarity with core data concepts and the Azure ecosystem before diving into Fabric specifics. This step establishes your data engineering vocabulary.
~1-2 months~1-2 months

Step 2 - Data pipeline engineering (ingestion and orchestration)
Build the pipeline engineering skills that move data from sources to storage. This is the operational foundation of data engineering—moving data reliably and efficiently.
~2-3 months~2-3 months
Step 2 - Data pipeline engineering (ingestion and orchestration)
Build the pipeline engineering skills that move data from sources to storage. This is the operational foundation of data engineering—moving data reliably and efficiently.
- Data Factory pipelines: Copy Data activity, linked services, datasets, incremental copy patterns
- Dataflows Gen2: Power Query transformations, data loading to Lakehouse or Warehouse
- Fabric Notebooks: PySpark for batch processing, reading/writing to Lakehouse tables
- Eventstreams: real-time ingestion from Event Hubs, Kafka, and custom sources

- ▸Configure an Eventstream to ingest streaming data and route to both Lakehouse and KQL Database.
- ▸Implement an incremental load pattern using Delta Lake MERGE INTO with WHEN MATCHED and WHEN NOT MATCHED.
Step 3 - Lakehouse architecture and transformation
Design and implement Lakehouse architectures with medallion layers. This is where raw data becomes business-ready data through systematic transformation.
~2-3 months~2-3 months
Step 3 - Lakehouse architecture and transformation
Design and implement Lakehouse architectures with medallion layers. This is where raw data becomes business-ready data through systematic transformation.
- Lakehouse architecture: Files section vs Tables section, Delta Lake format for managed tables
- Medallion architecture: Bronze (raw), Silver (cleansed), Gold (business-ready) layers
- Delta Lake operations: MERGE INTO, time travel with VERSION AS OF, VACUUM for log cleanup
- PySpark transformations: reading/writing Lakehouse tables, DataFrame operations, UDFs
- Fabric Warehouse: T-SQL endpoint, COPY INTO, cross-warehouse queries
- Real-Time Intelligence: Eventstream routing to KQL Database, KQL for real-time analytics
💡 Medallion architecture is central to Fabric. Bronze is raw, Silver is validated, Gold is business-optimized.
💡 Delta Lake MERGE INTO is the primary pattern for incremental loads. Know WHEN MATCHED, WHEN NOT MATCHED, and WHEN NOT MATCHED BY SOURCE.
🏁 Practitioner Level Checkpoint 2: You can design and implement Lakehouse architectures with medallion layers.
🛠 Project Ideas
- ▸Implement Delta time travel in a recovery scenario. Use VERSION AS OF and TIMESTAMP AS OF to query historical states.

~2-3 months~2-3 months
Step 4 - Data governance, security, and operations
Implement the governance, security, and operational practices that make data solutions enterprise-ready. This is what separates junior engineers from production-grade practitioners.
- Workspace configuration: capacity assignment, OneLake storage, Git repository connection
- Workspace lifecycle: development, test, and production stages, deployment pipelines
- Fabric security: workspace roles (Admin, Member, Contributor, Viewer), item-level permissions
- Row-level security: T-SQL predicates for Warehouses, SQL analytics endpoint for Lakehouses
- Microsoft Purview integration: scanning Fabric items, sensitivity labels, data lineage
- Capacity management: monitoring CU consumption, throttling, pausing, cost optimization
- Monitoring Hub: monitoring pipeline runs, Notebook executions, KQL ingestion
💡 Microsoft Purview integration is heavily tested. Know how scans work, how sensitivity labels propagate, and how lineage is tracked.
💡 RLS is implemented differently in Lakehouses (SQL analytics endpoint) versus Warehouses (T-SQL predicates).
🏁 Practitioner Level Checkpoint 3: You can secure, govern, and operate Fabric solutions at enterprise scale.
🛠 Project Ideas
- ▸Configure a Fabric workspace with Git integration and a branching strategy for development and production.
- ▸Implement row-level security in a Lakehouse and a Warehouse. Test access with different roles.

~1-2 months~1-2 months
Step 5 - Performance optimization and troubleshooting
Make data solutions fast, cost-effective, and reliable. Performance optimization and troubleshooting are what sustain production systems.
- Delta Lake performance: OPTIMIZE for file compaction, Z-ordering for multi-column filtering
- Spark performance: cluster configuration, executor sizing, caching DataFrames, broadcast joins
- Warehouse performance: statistics management, query store, result set caching
- KQL Database performance: ingestion time, query performance, materialized views

Final Step - What this path actually builds
This roadmap builds a professional data engineer who can design Lakehouse architectures, build production pipelines, secure and govern data solutions, and optimize for performance and cost. The most important message for 2026 - DP-203 is retired. DP-700 is the credential that matters now. If you have existing Azure data engineering experience (Synapse, ADF, ADLS), much of that knowledge transfers but OneLake, Lakehouse architecture, KQL, Eventstreams, and deployment pipelines are genuinely new. Before booking DP-700, ensure hands-on experience in Microsoft Fabric across all three domains. Build real pipelines. Measure your readiness with ExamOS. Book when your reasoning is sharp and your Lakehouse architectures are correct.
