> Sentry server returns full permission snapshot almost every 10 seconds. The desired behavior is to reduce the chance of getting full snapshot significantly.
> From debug message, we can see the returned change list is empty.
> That causes Sentry to send back full snapshot instead of delta changes. It has performance penalty because it takes much longer to get a full snapshot than getting the delta changes.
