Hi, I have a requirement to fetch all data from a collection. One way is to use streaming expression and other way is to use export.
Streaming expression documentation says *streaming functions are designed to work with entire result sets rather then the top N results like normal search. This is supported by the /export handler.* Also, Export handler documentation says *this feature uses a stream sorting technique that begins to send records within milliseconds and continues to stream results until the entire result set has been sorted and exported.* These two statements concludes to me that for fetching entire results streaming expressions uses export handler and export handler uses stream, so, whether I use streaming expression or export handler, they are internally same and would have same performance. I am correct over here to say so ?
