FlinkStreamletContext

abstract case class FlinkStreamletContext(streamletDefinition: StreamletDefinition, env: StreamExecutionEnvironment) extends StreamletContext with Product with Serializable

Runtime context for FlinkStreamlets

The FlinkStreamletContext provides the necessary context under which a streamlet runs. It contains the following context data and contracts:

  • An active StreamExecutionEnvironment that will be used to submit streaming jobs to the Flink runtime.
  • The Typesafe Config loaded from the classpath through a config method, which can be used to read configuration settings.
  • The name used in the blueprint for the specific instance of this streamlet being run.
  • A mapping that gives the name of the Kafka topic from the port name.
