Catching Up With Delta Lake in Azure Synapse
Conclusion. Delta Lake made an entrance into Azure Synapse Analytics by becoming generally available with Apache Spark 3.1 in September 2021. Its arrival provided expanded capabilities for the data lakehouse architecture in Azure Synapse Analytics bringing features such as ACID transactions, the MERGE statement, and time travel.

However we can use Synapse Notebooks with Spark SQL as a language which is very similar to TSQL to query Delta Tables. This allows you to time travel the data in a familiar language. 1) Add Delta Table to Lake Database. For easily querying Delta Tables you first need make the Delta Tables visible in Synapse by adding them to the Lake Database.
Use Delta Lake with Spark in Azure Synapse Analytics
The script provisions an Azure Synapse Analytics workspace and an Azure Storage account to host the data lake, then uploads a data file to the data lake. Explore the data in the data lake. After the script has completed, in the Azure portal, go to the dp000-xxxxxxx resource group that it created, and select your Synapse workspace.
Metadata-Based Ingestion in Synapse with Delta Lake
Create a new dataset using the linked service created in step 1 and keep the table name empty. 3. As shown in below snapshot, Create a pipeline that uses Look-up activity to read Metadata from Delta Lake. In this Look-up activity we are connecting to dataset (from point 2) to fire user customized query on Delta table.
