Hi Ryan,
>From the top of my head I can think only of one other option, which I haven’t tried myself yet. I recently noticed this <result> option ( http://community.marklogic.com/pubs/5.0/apidocs/Ext-6.html#xdmp:eval), which should be used in combination with xdmp:spawn if I understand correctly. Kind regards, Geert *Van:* [email protected] [mailto: [email protected]] *Namens *[email protected] *Verzonden:* woensdag 23 mei 2012 18:59 *Aan:* [email protected] *Onderwerp:* [MarkLogic Dev General] getting MarkLogic to execute functions in parallel I have a search function that calls other search functions that are independent of each other. The master search function takes the results of these sub-search functions and compiles and processes them according to some rules. I would like the sub-search functions to all execute in parallel at the same time to reduce the response time of the call to the master search function. I tried using xdmp:http-post and xdmp:invoke both in for loops and also without for loops. for example: *xdmp:http-post (for loop) does not execute in parallel: let $sub-search-results := for $sub-search in $sub-searches return xdmp:http-post($endpoint....) let $subsearch-results := <subsearch-results> {$sub-search-results} </subsearch-results> return $sub-search-results *xdmp:http-post (no for loop) DOES execute in parallel: let $sub-search-result-1 := xdmp:http-post($endpoint....) let $sub-search-result-2 := xdmp:http-post($endpoint....) let $sub-search-result-3 := xdmp:http-post($endpoint....) let $sub-search-result-4 := xdmp:http-post($endpoint....) let $subsearch-results := <subsearch-results> {$sub-search-result-1} {$sub-search-result-2} {$sub-search-result-3} {$sub-search-result-4} </subsearch-results> return $sub-search-results I tried similar approaches using xdmp:invoke (both with and without a for loop) but neither would execute in parallel. Does this sound right? I was expecting to be able to get parallel execution in a for loop using xdmp:http-post (I even tried fn:unordered but it had not effect). and I was expecting to get parallel execution using xdmp:invoke somehow but I couldn't. The http-post approach isn't too bad for my situation but it feels like a little bit of a hack just to get parallel execution. Are there any other ways? thanks, Ryan
