Method Details

add

public void add(ShardRouting shardRouting)

sort

public void sort(Comparator<ShardRouting> comparator)

size

public int size()

Returns the size of the non-ignored unassigned shards

getNumPrimaries

public int getNumPrimaries()

Returns the number of non-ignored unassigned primaries

getNumIgnoredPrimaries

public int getNumIgnoredPrimaries()

Returns the number of temporarily marked as ignored unassigned primaries

iterator

public RoutingNodes.UnassignedShards.UnassignedIterator iterator()

Specified by:

iterator in interface Iterable<ShardRouting>

ignored

public List<ShardRouting> ignored()

The list of ignored unassigned shards (read only). The ignored unassigned shards are not part of the formal unassigned list, but are kept around and used to build back the list of unassigned shards as part of the routing table.

ignoreShard

public void ignoreShard(ShardRouting shard,
 UnassignedInfo.AllocationStatus allocationStatus,
 RoutingChangesObserver changes)

Marks a shard as temporarily ignored and adds it to the ignore unassigned list. Should be used with caution, typically, the correct usage is to removeAndIgnore from the iterator.

See Also:

ignored(), RoutingNodes.UnassignedShards.UnassignedIterator.removeAndIgnore(AllocationStatus, RoutingChangesObserver), isIgnoredEmpty()

isEmpty

public boolean isEmpty()

Returns true iff this collection contains one or more non-ignored unassigned shards.

isIgnoredEmpty

public boolean isIgnoredEmpty()

Returns true iff any unassigned shards are marked as temporarily ignored.

See Also:

ignoreShard(ShardRouting, AllocationStatus, RoutingChangesObserver), RoutingNodes.UnassignedShards.UnassignedIterator.removeAndIgnore(AllocationStatus, RoutingChangesObserver)

shuffle

public void shuffle()

drain

public ShardRouting[] drain()

Drains all unassigned shards and returns it. This method will not drain ignored shards.
