Looking ahead to the new JSON SQL functions in Apache Flink® 1.15.0

Apache Flink 1.15.0 introduces new JSON SQL functions, allowing more powerful data processing. The use case focuses on IoT sensors that emit sensor reading messages in JSON format with possible nested JSON fields. With the help of these new functions, users can parse and build nested JSON data structures using only SQL statements. This feature will be available in version 1.15.0 but can already be explored by cloning Apache Flink's source code and building it yourself or waiting for the official release.
