createPlacementPlan

public PlacementPlan createPlacementPlan(PlacementRequest request,
                                         Set<ReplicaPlacement> replicaPlacements)

Description copied from interface: PlacementPlanFactory

Creates a PlacementPlan for adding replicas to a given shard(s) of an existing collection. Note this is also used for creating new collections since such a creation first creates the collection, then adds the replicas.

This is in support (directly or indirectly) of AddReplicaCmd, CreateShardCmd, ReplaceNodeCmd, MoveReplicaCmd, SplitShardCmd, RestoreCmd, MigrateCmd as well as of CreateCollectionCmd.

                                               Replica.ReplicaType replicaType)

Description copied from interface: PlacementPlanFactory

Creates a ReplicaPlacement to be passed to PlacementPlan factory methods.

Note the plugin can also build its own instances implementing ReplicaPlacement instead of using this call (but using this method makes it easier).
