REST message and long response times

[Ravish Shetty]

Hi all,

I have a case where I am calling the REST API of an orchestrating tool from a RITM workflow.

The tool might take around 10 to 20 minutes to process the request and send a response. Below is the code that I have which will be inside the 'run script' activity of the workflow.

var requestUpdateSet = new sn_ws.RESTMessageV2();
requestUpdateSet.setEndpoint(endpoint);
requestUpdateSet.setHttpMethod('GET');
requestUpdateSet.setRequestHeader("Accept", "application/json");
requestUpdateSet.setMIDServer('xyz');

//requestUpdateSet.setHttpTimeout(10000);
var obj = requestUpdateSet.execute();

Will the REST message code above wait for the whole 10 -20 minutes of the tool to send back the response or does it work asynchronously? So far i have seen that it works synchronously when the processing takes around 20-60 seconds but I have not dealt with the case yet when it takes 10 minutes or more.

Edit:

We already have the below property added to remove the default 30 seconds timeout limit

Thanks,

Ravish

Hi, you might find this HI article gives you the details\the answers you need

From personal experience, timeouts of any significance are poor platform performance just waiting to happen; To compond the problem degraded performance from timeouts can be self perpetuating, and even small timeouts become bigger issues as a platforms get busier over time.

If I was seeing 10-20 minute response times from any integration, my first action would be to engage the project/management team responsible for the functionality and make it clear that the solution is a business risk and that this needs to be accepted or an alternative found.

Try using executeAsync() instead of execute().
