Validating and activating a pipeline
The use of object properties in a pipeline is validated regardless of whether the Mapping activity is part of the pipeline model or the Table activity defines the correspondence between object properties and table columns. Mapping validation is performed when a pipeline is started. You are notified about any inconsistencies through the notification panel.
You cannot start a pipeline if any unmapped properties exist. However, you can start a pipeline with warnings when, for example, properties are mapped to incorrect data types or one or more used properties are no longer available from the previous activities. If an event is streamed to mismatched data types, for example, a string is inserted into an integer column, then, depending on the database that handles the event, the event can be moved to the Replay Queue as an error for further investigation.
To ensure the accuracy of the data type mapping, see "Supported databases".
