Summary

User is having an external Rest service which takes longer time to respond (5mins). In this case, user wants to know the impact of keeping the response time-out attribute to 5mins on the Connect-REST rule form.

Requested for the below information -

What is the ideal value for setting the Response Time-out ? Any side effects ?
or any other alternation suggestions ?

Resolution

The explanation for this behavior is as follows: 

1. Response Timeout value (milliseconds) is just a threshold value like "when do I give up?"

2. It is a best practise to have threshold value not more than 1-2 mins.

3. If your external rest service taking up longer time to respond, let’s say 5 mins, it is not that advisable to keep response timeout value to 5 mins, as the user just have to wait for 5 mins on the same screen. (Consider fine-tuning the REST service).

4. In the above case (5mins) there might be a chance of getting a thread hung as the thread will go into the activity code and will have to wait on that.

5. On your screens, consider using data pages where you can source it from Connect-REST service and define your refresh strategies to load the data when required.
