> Today, we have a config that determines the number of applications that can be stored in the state-store. Since there is no easy way to figure out the maximum number of running applications at any point in time, users are forced to use a conservative estimate. Our default ends up being even more conservative.
> It would be nice to allow storing all running applications with a conservative upper bound for it. This should allow for shorter recovery times in most deployments.
