 external storage operations to scale well even when a Task carries many large payloads.
 
+When a payload is offloaded to external storage, the Temporal UI displays a reference token instead of the actual data.
+This is expected. Your application code receives the fully decoded result because the SDK transparently retrieves the

 Because External Storage runs after the Payload Codec, if you use an encryption codec, payloads are already encrypted
 before upload to your store.
