streaming

go-streaming is a framework that combines stream processing and stream computing capabilities

Components

There are three basic components of a construction stream application.

Source

Source is the end point of the data (etc. Http Kafka...) and needs to implement component.Source interface.

Operator(OneInput and TwoInput)

Operator is divided into OneInputOperator and TwoInputOperator, OneInputOperator to process single-stream data, TwoInputOperator is used to merge multiple single streams to achieve the purpose of aggregation processing. Their interfaces are all component.Operator, which can be distinguished by whether to implement processEvent1 and processEvent2 func.

Sink

Sink is the end point of the data, which can be sent to other components or output at the terminal (as long as you want) and needs to implement component.Sink interface.
