Azure Databricks vs Synapse Spark
Azure Databricks vs Azure Synapse Spark – Which Should You Choose?
In today’s modern data platforms, choosing the right big data processing engine is critical. If you are learning through Azure Data Factory training or building enterprise-grade analytics solutions, you’ve likely encountered two powerful Spark-based services: Azure Databricks and Azure Synapse Spark.
What is Azure Databricks?
Azure Databricks is a fully managed Apache Spark platform optimized for large-scale data processing, machine learning, and advanced analytics.
It provides:
-
Collaborative notebooks (Python, Scala, SQL, R)
-
Auto-scaling clusters
-
Delta Lake support
-
ML integration
-
Advanced Spark optimization
Azure Databricks is widely used in enterprise data lakehouse architectures and supports complex ETL, streaming, and AI workloads.
What is Azure Synapse Spark?
Azure Synapse Spark is the Apache Spark capability integrated within Azure Synapse Analytics.
It allows users to:
-
Run Spark jobs inside Synapse workspace
-
Combine SQL analytics with big data processing
-
Integrate with Synapse pipelines
-
Use serverless or dedicated SQL pools alongside Spark
Azure Synapse Spark is ideal for organizations that want a unified analytics platform combining data warehousing and big data processing.
Architecture Comparison
| Feature | Azure Databricks | Azure Synapse Spark |
|---|---|---|
| Platform Type | Dedicated Spark Service | Spark inside Synapse |
| Workspace | Separate Databricks Workspace | Unified Synapse Workspace |
| Integration | Strong ML & Delta Lake | Strong SQL + Spark integration |
| Dev Experience | Notebook-focused | Studio-based analytics |
| Pipeline Integration | Works with ADF | Built-in Synapse Pipelines |
Performance Comparison
Azure Databricks
-
Optimized Spark runtime
-
Better auto-scaling control
-
Stronger ML workloads
-
Advanced Delta Lake performance tuning
Azure Synapse Spark
-
