ADLSGen1 Data Model
This section shows the available API objects and provides more information on executing SQL to Azure Data Lake Storage APIs.
- The driver models Azure Data Lake Storage entities like documents, folders, and groups as relational views, allowing you to write SQL to query Azure Data Lake Storage data.
- Stored procedures allow you to execute operations to Azure Data Lake Storage.
- Live connectivity to these objects means any changes to your Azure Data Lake Storage account are immediately reflected when using the driver.
Views describes the available views. Views are statically defined to model Resources and Permissions.
Stored Procedures are function-like interfaces to Azure Data Lake Storage. Stored procedures allow you to execute operations to Azure Data Lake Storage, including downloading documents and moving envelopes.
Collaborative Query Processing
The driver offloads as much of the SELECT statement processing as possible to Azure Data Lake Storage and then processes the rest of the query in memory. API limitations and requirements "are also documented in this section.
See SupportEnhancedSQL for more information on how the driver circumvents API limitations with in-memory client-side processing.
