类 SearchFacadeStream

java.lang.Object

org.apache.solr.client.solrj.io.stream.TupleStream

org.apache.solr.client.solrj.io.stream.SearchFacadeStream

所有已实现的接口:

Closeable, Serializable, AutoCloseable, Expressible, MapSerializable, MapWriter, NavigableObject

public class SearchFacadeStream
extends TupleStream
implements Expressible

Connects to Zookeeper to pick replicas from a specific collection to send the query to. Under the covers the SolrStream instances send the query to the replicas. SolrStreams are opened using a thread pool, but a single thread is used to iterate and merge Tuples from each SolrStream.

从以下版本开始:

5.1.0
