Final answer:
Spark SQL handles both structured and semi-structured data, and can run real-time data processing. It does not store data in NoSQL databases or generate machine learning models, as these tasks are handled by other components or technologies.
Step-by-step explanation:
Functions of Spark SQL
Apache Spark SQL is a component of the open-source Apache Spark framework that supports processing structured and semi-structured data. As such, it can:
- Process structured and semi-structured data, integrating with multiple data sources including JSON, Hive, Avro, etc.
- Run real-time data processing, executing SQL queries on streaming data.
However, Spark SQL is not designed for:
- Storing data in a NoSQL database. Instead, it reads from and writes to various data sources.
- Generating machine learning models. While Spark SQL can prepare and manipulate data, model generation is typically done using the Spark MLlib component.
Spark SQL's combination of SQL with Spark's functional programming API gives it powerful capabilities in data processing and analytics.
