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.
