Can we disable an annotation at runtime?

Hi

As part of adding Fault Tolerance to our existing project, I want to know if I can disable them at runtime in case something goes wrong in the early releases. I tried to set the following at runtime in System.properties and seems ineffective:

Timeout/enabled=false

When I restart the system, then it gets disabled. So, apparently configurations are being read only once in system startup and changing them at runtime has no effect. But I could not find this mentioned in documentation explicitly. So I just wanted to be sure my interpretation is correct and also suggest to add this minor detail to the spec to avoid misinterpretation.

Yes, all of the configuration are static and only read once at the application starting to avoid inconsistent behaviour.

I checked the spec, which only states one of the configurations being read only. The spec would need to state that the same rule is applicable to all configurations.

In order to prevent from any unexpected behaviours, the property MP_Fault_Tolerance_NonFallback_Enabled will only be read on application starting. Any dynamic changes afterwards will be ignored until the application restarting.

Thanks Emily for the quick answer 🙂
