Package org.apache.solr.cluster.placement

Interface PlacementPlan

public interface PlacementPlan

A fully specified plan or instructions for placement, deletion or move to be applied to the cluster.

Fully specified means the actual Node's on which to place replicas have been decided.

Instances are created by plugin code using PlacementPlanFactory. This interface obviously doesn't expose much but the underlying Solr side implementation has all that is needed (and will do at least one cast in order to execute the plan, likely then using some type of visitor pattern).
