Application extracting Data from Unity Catalogue

Dear Databricks community,

I'm seeking advice on the best method for applications to extract data from the Unity catalogue. One suggested approach is to use JDBC, but there seems to be a dilemma. Although using a job cluster has been recommended due to its cost-effectiveness, it appears that JDBC isn't supported in this environment and is only available for general-purpose clusters. What is the recommended approach in this situation?

What exacltly do you mean by 'extracting'?  If you want to load tables defined in Unity into a database, I would indeed do this using job clusters and a notebook.
If you want to extract some data once in a while into a csv f.e., you could perfectly do that with any sql tool using odbc or even in databricks ui itself.

Or do you want to have some kind of a SQL api where applications can run queries?

"extracting" as in end applications query data from unity catalog.  For example, end application such as 'react app' or django app to query data upon user's request.  I have millions of IoT data streaming to Databricks, and I've streaming job ETL to structure the data, then I would like end applications to query the data by device id, by time, by region for example.

Interesting.
There is a SQL statement api:
