Trigger autorefresh

Trigger autorefresh

1. Can we trigger autorefresh using ServiceInvokecompleted of any service?? (without using refresh intervel)

 

2. While using autorefresh in cloud for every 10 mins, it is reloading all the services binded to the mashup right? If 500 users using same mashup simultaneously, it will slow down the server performance?? What issues we can expect from this scenario?

AutoRefresh specifically ties to fire desired services, so it does not reload all services.

Your 'refresh event' is bound to whatever services you want it to bind to, only those services fire, bring back a payload and that is then reflected on the mashup.

Is it will affect the performance if 500 users using same mashup which have autorefresh?

Each mashup runs on their specific client machine, so generally speaking the autorefresh is based on 'time elapsed' like 30 seconds. So it is unlikely that all 500 will trigger refresh at the exact same time. So in that respect I don't think performance should be affected.

Okay Thanks. I want autorefresh to be triggered for every 15 mins as well as if any particular serviceInvoke completed. Shall we use these 2 cases on single autorefresh.?

HI @AP_9587236.

 

The autorefresh is timer based, whereas the serviceInvokeComplete will need to be bound to whatever you want to refresh.  So basically, you will have refreshes running more often than every 15 minutes.  

 

For example:  If you have a value stream with frequently updating number property values, you can bind the QueryNumberPropertyHistory service to the autofresh event so that every 15 minutes it will refresh the values that have come in.  If you wanted to do something outside of that refresh cycle based on another service execution, you can use the ServiceInvokeComplete event to bind it to QueryNumberPropertyHistory instead of binding it to autorefresh.

Hi @AP_9587236

 

To tack on to the previous responses, there are a number of factors that will affect performance such as memory allocated to java, number of cores, number of users logged in, network performance, etc.  Therefore, you need to stress test your solution to determine if tweaking will be needed for your specific situation prior to going live in production.
