PI Analysis Service should pick up change in Cache Refresh Interval of AF Tables

It would be nice if the PI Analysis Service could pick up a change in the Cache Refresh Interval of any AF Table being referenced by input attributes with a table lookup data reference. Currently, a service restart is required.

    We have so many analyses on our server that it takes around 24 hours from restarting until it is fully functional. So having to restart the analysis service each time we need a refresh is not feasible. Hope an improvement can be made here!

    This would be helpful! It is very tricky since it seems that PSE shows the correct value yet the analysis reads from a separate cache.

    I'm a little surprised that it doesn't notice the change already. This is behaviour that I would have assumed the analysis service had. We should not have to restart the analysis service after changing AF configurations.

    I was also surprised to find out that this isn't automatic. Perhaps this request doesn't have a lot of votes because most people don't even realize this is the case.

    This is also a major bug in PSE, where the latest version of Tables is cached locally, and even when you Refresh the application, it doesn't pick up changes applied by other users to any tables you have cached, which can lead to conflicting behaviours if you then try to update that same table yourself.
