    Input and Output Components

    The visually larger Input and Output components represent service’s HTTP request and response. You should place your service logic in between the two components.

    Input and Output are two special components of Data Service REST job. Their attribute editors allow alternative access to the REST endpoint input and output configuration eliminating the need to switch to the Endpoint Configuration tab.

    The Input component provides you with a stream of input data. If the component reading the request body is in the lowest phase of the job, the same as the Input component, then the data can be read before the whole request body arrives. This is useful when the request body has a larger size and/or the network connection is slow. If the component reading the request body is not in the lowest phase of the job then the whole request body will be read and cached by the input component.

    If you connect any edge to a port on the Output component, all records flowing through this edge will be used as a response payload. Before sending, the records are automatically serialized using one of the automatic serialization formats (JSON, XML or CSV) according to Endpoint Configuration.

    For detailed information about data serialization, see the Generating response content section.
