+ [Transform data using operators in Managed Service for Apache Flink with the DataStream API](how-operators.md): These components transform or group data elements within your application.
+ [Track events in Managed Service for Apache Flink using the DataStream API](how-time.md): This topic describes how Managed Service for Apache Flink tracks events when using the DataStream API.
