public class ClusterInfo
extends Object

ClusterInfo is an object representing a map of nodes to DiskUsage and a map of shard ids to shard sizes, see InternalClusterInfoService.shardIdentifierFromRouting(String) for the key used in the shardSizes map

ClusterInfo

public ClusterInfo(Map<String,DiskUsage> leastAvailableSpaceUsage,
           Map<String,DiskUsage> mostAvailableSpaceUsage,
           Map<String,Long> shardSizes,
           Map<ShardRouting,String> routingToDataPath)

Creates a new ClusterInfo instance.

Parameters:

leastAvailableSpaceUsage - a node id to disk usage mapping for the path that has the least available space on the node.

mostAvailableSpaceUsage - a node id to disk usage mapping for the path that has the most available space on the node.

shardSizes - a shardkey to size in bytes mapping per shard.

routingToDataPath - the shard routing to datapath mapping
