Scenario: You need to implement a windowed aggregation operation on streaming data in Apache Flink. Which API would you use, and why?
- DataStream API
- ProcessFunction API
- SQL API
- Table API
You would use the Table API in Apache Flink for implementing a windowed aggregation operation on streaming data. The Table API provides a higher-level abstraction for stream processing, allowing developers to express complex computations using SQL-like queries and operators. It offers built-in support for windowed aggregations, making it convenient for tasks such as calculating aggregates over sliding or tumbling windows efficiently.
