Summary
When working with Azure Data Factory (ADF) and Azure Synapse Analytics using the serverless SQL pool, it’s essential to understand which linked service to use for dataset creation. The recommended approach is to use the Azure Synapse Analytics (SQL) linked service, which allows for seamless integration with the serverless SQL pool.
Root Cause
The confusion arises from the fact that some tutorials recommend creating a dedicated Synapse linked service, while others suggest using the built-in serverless SQL pool. The root cause of this confusion is the difference in setup and configuration between the two approaches. Key factors to consider include:
- Serverless SQL pool configuration
- Linked service recommendations
- Dataset creation best practices
Why This Happens in Real Systems
In real-world systems, this issue occurs due to:
- Misconfiguration of Azure Synapse Analytics and ADF
- Lack of understanding of the serverless SQL pool and its integration with ADF
- Insufficient documentation or outdated tutorials
- Variations in setup and configuration between different environments
Real-World Impact
The impact of using the incorrect linked service can result in:
- Failed dataset creation
- Inconsistent data integration
- Performance issues with ADF and Azure Synapse Analytics
- Increased costs due to inefficient resource utilization

SELECT * FROM sys.tables;How Senior Engineers Fix It
Senior engineers fix this issue by:
- Verifying the setup and configuration of Azure Synapse Analytics and ADF
- Selecting the correct linked service (Azure Synapse Analytics (SQL)) for dataset creation
- Ensuring proper configuration of the serverless SQL pool
- Testing and validating the integration between ADF and Azure Synapse Analytics
Why Juniors Miss It
Junior engineers may miss this issue due to:
- Lack of experience with Azure Synapse Analytics and ADF
- Insufficient understanding of the serverless SQL pool and its integration with ADF
- Reliance on outdated tutorials or insufficient documentation
- Inadequate testing and validation of the integration between ADF and Azure Synapse Analytics
