I have not tried this first hand however, from what I know, you have 2 options here.
The easy way is to use Azure Databricks Delta Lake linked service. In the setting you can mention the cluster id but this cluster id should correspond to an interactive cluster. Something like 0409-035326-4alfp636. If you try to point it to a Sql warehouse cluster, you will get an error saying that the cluster cannot be found. So you cannot use a Databricks SQL endpoint with this option but you can still read a Delta table. If the cluster is off, the pipeline execution will bring up the cluster and then execute your query.
The hard way is to use the ODBC linked service. However, this requires you to use a self hosted integration runtime. You cannot use the standard AzureIR. Install the required ODBC drivers on the SHIR and then use the ODBC linked service to connect to the Databricks SQL endpoint. You can refer to the Microsoft documentation on creating a ODBC linked service here. You can refer to the Databricks ODBC details as mentioned here.
Azure Databricks Delta Lake (Dataset) uses a linked service that can only connect to a All Purpose/Interactive cluster.
If you want to use the SQL Endpoint, you would need a Self Hosted Integration Runtime for ADF with Databricks ODBC driver Installed on it. In ADF, the linked service would be a ODBC Linked Service
@Retired_mod Thanks for the information, however, this query was about the Databricks SQL endpoint (which is like an engine to execute queries in Databricks)
