What is the difference between a lazy operator and a stream capable one?

Question

Certain functions and operations in DataWeave seem to execute in a lazy manner, not loading all records at once or only executing when called. At the same time, some seem to support streaming. What's the difference between the two?

If the incoming payload is streamcapable. it cannot be accessed more than once and we can access it only in a sequential manner.
