FlinkIntermediateRawSource

Source with typical source stream trasformations:

adds source using provided SourceFunction (here raw source produces raw data) 2. sets UID 3. assigns timestamp and watermarks 4. initializes Context that is streamed within output DataStream (here raw data are mapped to Context) It separates raw event data produced by SourceFunction and data released to the stream as Context variables. By default it uses basic "single input value" implementation of initializer, see BasicFlinkContextInitializer.

Raw: - type of raw event that is generated by flink source function.

Self Type: FlinkIntermediateRawSource[Raw] with Source[Raw]
