Input components are the components generally placed at the beginning of a Talend job. They are in charge of retrieving the data that will later be processed in the job.
An input component is primarily made of three distinct logics: - The execution logic of the component itself, defined through a partition mapper. - The configurable part of the component, defined through the mapper configuration. - The source logic defined through a producer.
Before implementing the component logic and defining its layout and configurable fields, make sure you have specified its basic metadata, as detailed in this document.
