类 Suggester

java.lang.Object

org.apache.solr.client.solrj.cloud.autoscaling.Suggester

所有已实现的接口:

MapSerializable, MapWriter, NavigableObject

直接已知子类:

MoveReplicaSuggester, NoneSuggester, UnsupportedSuggester

public abstract class Suggester
extends Object
implements MapWriter

A suggester is capable of suggesting a collection operation given a particular session. Before it suggests a new operation, it ensures that , a) load is reduced on the most loaded node b) it causes no new violations

构造器详细资料

Suggester

public Suggester()

方法详细资料

hint

public Suggester hint(Suggester.Hint hint,
                      Object value)

getAction

public CollectionParams.CollectionAction getAction()

forceOperation

public Suggester forceOperation(boolean force)

Normally, only less loaded nodes are used for moving replicas. If this is a violation and a MOVE must be performed, set the flag to true.

isNodeSuitableForReplicaAddition

protected boolean isNodeSuitableForReplicaAddition(Row targetRow,
                                                   Row srcRow)

getSuggestion

public SolrRequest getSuggestion()

getWithCollection

protected Optional<String> getWithCollection(String collectionName)
                                      throws IOException

抛出:

IOException

getSession

public Policy.Session getSession()

isAllowed

protected boolean isAllowed(Object v,
                            Suggester.Hint hint)

toString

public String toString()

覆盖:

toString 在类中 Object

writeMap

public void writeMap(MapWriter.EntryWriter ew)
              throws IOException

指定者:

writeMap 在接口中 MapWriter

抛出:

IOException

setupWithCollectionTargetNodes

protected Collection setupWithCollectionTargetNodes(Set<String> collections,
                                                    Set<Pair<String,String>> s,
                                                    String withCollection)
