Data Integration

shows complex data cells as hyperlinks on the

Preview

page. When you click a hyperlink, the preview data appears in a separate panel. Preview results show null values for the job name, start time, end time, and job status columns.

Preview results for the Sequence Generator transformation might not be consistent from one preview run to the next. For example when you set the initial value in the transformation to 1, you might get a result of 1, 2, 3, 4 the first time you run a preview. The second time you run a preview, you might get 2001, 2002, 2003, 2004.

If the selected transformation is available only in advanced mode or contains hierarchical data,

Data Integration

stores preview results in a JSON file. Otherwise,

Data Integration

stores preview results in a CSV file.

Data Integration

purges preview data every 30 minutes and deletes preview data when the cluster shuts down.
