| '''Summary'''|Similar This function executes the supplied (non-updating) functions in parallel.|-| '''Examples'''|* The following function sleeps in parallel; it will be finished in 1 second if your system has at least 2 cores:<pre class='brush:xquery'>xquery:fork-join( for $i in 1 to 2 return function() {prof:sleep(1000) })</pre>* In the following query, up to four URLs will be requested in parallel:<pre class='brush:xquery'>let $funcs := for $segment in 1 to 4 let $url := 'http://url.com/path' || $segment return function() {Code|fnhttp:tracesend-request((), $expr, url) }return xquery:fork-join($msgfuncs)</pre>|-|'''Errors'''|{{Error|unexpected|#Errors}}, but instead of an unexpected error occurred while running a query or function in a user-defined message, it emits the compile-time type and estimated result size of its argumentseparate thread.
