| .Autoscaling is deprecated |

| [.lead] |
| The goal of autoscaling is to make SolrCloud cluster management easier by providing a way for changes to the cluster to be more automatic and more intelligent. |
| |
| Autoscaling includes an API to manage cluster-wide and collection-specific policies and preferences and a rules syntax to define the guidelines for your cluster. Also included are features to utilize the policies and preferences so they perform actions automatically when certain conditions are met. |
