data cache problems

[jinxiao]

when i use a json api datasource , i found a data cache problem.
i tried to update my json api , but the result on grafana not changed .
when i use curl command , it could show latest result , but grafana cannot.

What have you set the Cache time to? By default it caches the response for 5 minutes. If you want to disable caching, you can set it to 0 seconds.

well , i have already tried it, it not always worked .
let me take an example ,
i change the datasource url, and set the cache time to zero, what showed in query inspector is still the old datasource

Good point. We should probably invalidate the cache if the data source configuration has changed, which I don't believe we do today.
