> It's not always clear what would be the final state of the cluster after 
> applying the suggested changes (obtained from {{/autoscaling/suggestions}}), 
> especially on a large and busy cluster where several autoscaling rules have 
> to be considered.
> This issue proposes to use the simulation framework for simulating the 
> effects of the suggestions.
> First, the simulator would be initialized from the current state of a real 
> cluster. Then it would run several rounds of simulated execution of 
> suggestions until there were either no more suggestions (the cluster would be 
> perfectly balanced) or the iteration count limit was reached.
> This simulation could be executed using either the deployed autoscaling 
> config or one provided by the user, which would make it easier to test the 
> effects of various configurations on the cluster layout.
> Support for this functionality would be integrated into the existing 
> {{SolrCLI autoscaling}} tool.
