How do you turn dynamic mode on and off for reader feature types already on the canvas?

• A. The Merge Feature Type checkbox on a reader feature type
• B. Right-clicking the reader feature type and checking/unchecking Dynamic
• C. Finding the reader in the Navigator and setting the Feature Type Definition Mode under Parameters
• D. Adding a DynamicModeSetter transformer connected to the reader feature type

Answer: (B)

Dynamic mode lets a reader adapt to data where feature types or attributes can change at runtime. If a reader is already on the canvas, you can enable or disable this behavior directly on that feature type. Right-click the reader feature type and check or uncheck the Dynamic option. This applies immediately to that reader instance on the canvas, making it the simplest and most direct way to control whether the reader can create new feature types on the fly. The other approaches don’t provide a direct per-reader toggle on the canvas or involve changing definitions from the Navigator or adding a transformer, which isn’t how dynamic mode is controlled.
