Class Partition

  • All Implemented Interfaces:
    com.github.ambry.clustermap.PartitionId, com.github.ambry.clustermap.Resource, java.lang.Comparable<com.github.ambry.clustermap.PartitionId>
    public class Partition
extends java.lang.Object
implements com.github.ambry.clustermap.PartitionId
    An extension of PartitionId to be used within the StaticClusterManager. A Partition is the unit of data management in Ambry. Each Partition is uniquely identifiable by an ID. Partitions consist of one or more Replicas. Replicas ensure that a Partition is available and reliable.
