All Implemented Interfaces:

java.lang.Iterable<ShardIterator>

public class GroupShardsIterator
extends java.lang.Object
implements java.lang.Iterable<ShardIterator>

This class implements a compilation of ShardIterators. Each ShardIterator iterated by this Iterable represents a group of shards. ShardsIterators are always returned in ascending order independently of their order at construction time. The incoming iterators are sorted to ensure consistent iteration behavior across Nodes / JVMs.
