tThresholdViolationAlert Standard properties

Schema and Edit schema

A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either Built-in or stored remotely in the Repository.

Built-in: You create and store the schema locally for this component only. Related topic: see Talend Studio User Guide.

Repository: You have already created the schema and stored it in the Repository and thus reuse it when needed. Related topic: see Talend Studio User Guide.

Output field

Select in the list the output field that will hold the input data.
