Schema and Edit
Schema

A schema is a row description. It defines the number of fields
(columns) to be processed and passed on to the next component. When you create a Spark
Job, avoid the reserved word line when naming the
fields.

The schema of this component is read-only. You can click
Edit schema to view the schema.

This read-only payload column is used to carry the body
of the request to be processed. Note that you must define a same payload column in the schema of the preceding component to send data to this
read-only column.

URL

Enter the URL address of the REST Web server to be invoked.

HTTP Method

From this list, select an HTTP method that describes the desired action. The specific
meanings of the HTTP methods are subject to definitions of your Web service provider. Listed
below are the generally accepted HTTP methods:

• PUT: updates data based on the given parameters, or
  if the data does not exist, creates it.

• POST: creates and uploads data based on the given
  parameters.

• DELETE: removes data based on the given parameters.

HTTP Headers

Enter the name-value pair(s) for HTTP headers to define the parameters of the requested
HTTP operation.

For the specific definitions of HTTP headers, consult your REST Web service provider. For
reference information, visit en.wikipedia.org/wiki/List_of_HTTP_headers.

Use SSL/TLS

Select this check box to enable the SSL or TLS encrypted connection.

Then you need to use the tSetKeystore
component in the same Job to specify the encryption information.

Usage rule

This component is used as an end component and requires an input link.

This component, along with the Spark Streaming component Palette it belongs to, appears
only when you are creating a Spark Streaming Job.

Note that in this documentation, unless otherwise explicitly stated, a scenario presents
only Standard Jobs, that is to say traditional
Talend
data
integration Jobs.

Spark Connection

This connection is effective on a per-Job basis.
