Abhishek Narain has an announcement:
Today, we are introducing support for orchestrating Synapse notebooks and Synapse spark job definitions (SJD) natively from Azure Data Factory pipelines. It immensely helps customers who have invested in ADF and Synapse Spark without requiring to switch to Synapse Pipelines for orchestrating Synapse Notebooks and SJD.
NOTE: Synapse notebook and SJD activities were only available in Synapse Pipelines previously.
If you’re familiar with Synapse Pipelines, the equivalent ADF operations are extremely similar, as you’d probably expect.
