Data Object Validation

Data Object Validation

When you validate a mapping, the Developer tool verifies the source and target data objects that are part of the streaming mapping.
The Developer tool generates an error in the following scenarios:
  • The mapping contains a source data object other than Kafka or JMS, and target data object other than Kafka, complex file, or relational data object.
  • The read and write properties of the Kafka, JMS, and complex file data objects are not specified correctly.
  • If you add a Kafka or a JMS data object to an LDO mapping, REST mapping, or a mapplet.


We’d like to hear from you!
