Which is NOT a feature of Databricks Photon?

The correct choice indicates that support exclusively for traditional SQL querying is not a feature of Databricks Photon. Databricks Photon is designed to enhance performance for various types of queries, particularly those involving complex data operations like aggregations and joins. It leverages an execution engine that optimizes query performance, especially for large datasets.

Photon supports a wide range of SQL operations beyond just traditional SQL querying, including advanced analytical functions, making it suitable for a variety of data processing and analysis needs. Therefore, stating that it supports only traditional SQL querying misrepresents its capabilities, as it is built to handle modern data scenarios and improve efficiency across diverse query types.

In contrast, options highlighting robust scan performance, faster writing operations for Delta and Parquet formats, and acceleration of queries with aggregations and joins accurately reflect Photon’s strengths in performance and versatility.
