xdmp:streamable

xdmp:streamable(
   $value as item()*
) as xs:string*

Summary

Returns a sequence of strings describing the streaming nature of the argument value.

Usage Notes

String values returned include zero or more of the following:

• future: The whole result requires more processing time for execution to be completed.
• iterator: The result is a sequence that is calculated one value at a time as required.
• concurrent: The result is being calculated concurrently in a separate thread. This might also be because the result is waiting on network or IO.

Example

xdmp:streamable(cts:search(fn:doc(), "hello"))
=> "iterator"
