Apache Flink 1.18.0 introduces a multitude of enhancements, including a JDBC Driver for the Flink SQL Gateway, allowing users to interact with tables via SQL clients that support JDBC. The update also facilitates the use of stored procedures within Flink connectors, enabling easier and potentially optimized data operations. New commands such as REPLACE TABLE AS SELECT now support atomicity, while TRUNCATE TABLE is available in batch mode. Time travel SQL syntax is supported for querying historical data versions, and operator-level state time-to-live (TTL) settings are introduced for stream regular joins. Additional improvements include Hybrid Shuffle for remote storage, runtime filters for optimized join performance, and the Adaptive Scheduler for better elasticity and resource management. Flink now runs on Java 17, and enhancements in SQL client usability and batch processing performance have been implemented. The update marks a shift from Akka to Apache Pekko due to licensing changes and includes upgrades to Apache Calcite, enhancing Flink's query optimization capabilities. The community continues to focus on cloud-native integration and prepares for the upcoming Flink 2.0 release by deprecating certain legacy APIs.
