Connect Stream

Synopsis​

This operator performs a connect operation on two data streams in a streaming analytic workflow.

Description​

This is a streaming operator and needs to be placed inside a Streaming Nest or a Streaming Optimization operator. The operator defines the logical functionality and can be used in all streaming analytic workflow for any supported streaming platform (currently Flink and Spark). The actual implementation used depends on the type of connection connected to the Streaming Nest operator in which this operator is placed.

Input​

control stream​

The control input stream of this stream connect operation. It needs to receive the output of a preceding streaming operator, to define the flow of data events in the streaming analytic workflow.

data stream​

The data input stream of this stream connect operation. It needs to receive the output of a preceding streaming operator, to define the flow of data events in the streaming analytic workflow.

Output​

output stream​

The connected output of this stream connect operation. Connect it to the next Streaming operator to define the flow of the data events in the designed streaming analytic workflow.

Parameters​

Control key​

Key of the value to be used on the control-stream.

Data key​

Key of the value to be used on the data-stream.
