Rules and Guidelines for Data Preview on the Spark Engine

Rules and Guidelines for Data Preview on the Spark Engine

Consider the following rules and guidelines when you work with data preview on the Spark engine:
  • You cannot preview data in a mapping in which the preview point or any upstream transformation contains dynamic complex data types, such as dynamic arrays, dynamic maps, and dynamic structs.
  • Date fields have an additional timestamp component (00:00:00) in the data viewer.
  • You can view the logs in the following location:
    <Install location>/logs/<node name>/services/DataIntegrationService/disLogs/ms
    . You cannot view the logs from the Developer tool.
  • You cannot preview data on an Expression transformation configured for windowing.
  • You cannot preview data on transformations that contain multiple output groups.
