Can you please let me know how can we expose virtual/Physical dataset as an API
The Catalog REST API (http://docs.dremio.com/rest-api/catalog/) allows creating/updating/deleting of datasets. The SQL API (http://docs.dremio.com/rest-api/sql/post-sql.html) allows you to run queries against datasets.
How can generate authorization key on dremio in order to access data as rest api? I need pass detail on postman for same.
Is it possible to expose the actual data via API - the catalog API is at a metadata level.
You can use the SQL api to run queries and fetch the results.
