This lesson gives an introduction into Flink’s DataStream API.
You will become familiar with
- the basic concepts and building blocks of the DataStream API,
- record-at-a-time operators and functions, and
- Flink’s type system.
Later you will
- write your first Flink stream program using the DataStream API,
- compile and package your program using Maven, and
- execute your program on a (locally) running Flink instance.
