Constructor Detail

Builder

protected Builder()

Constructor for use by subclasses. This constructor was public prior to version 9.0

Builder

public Builder(List<String> solrUrls)

Provide a series of Solr URLs to be used when configuring CloudLegacySolrClient instances. The solr client will use these urls to understand the cluster topology, which solr nodes are active etc.

Provided Solr URLs are expected to point to the root Solr path ("http://hostname:8983/solr"); they should not include any collections, cores, or other path components.

Usage example:

   final List<String> solrBaseUrls = new ArrayList<String>();
   solrBaseUrls.add("http://solr1:8983/solr"); solrBaseUrls.add("http://solr2:8983/solr"); solrBaseUrls.add("http://solr3:8983/solr");
   final SolrClient client = new CloudSolrClient.Builder(solrBaseUrls).build();
 

Builder

public Builder(ClusterStateProvider stateProvider)

Provide an already created ClusterStateProvider instance

Builder

public Builder(List<String> zkHosts,
               Optional<String> zkChroot)

Provide a series of ZK hosts which will be used when configuring CloudLegacySolrClient instances.

Usage example when Solr stores data at the ZooKeeper root ('/'):

   final List<String> zkServers = new ArrayList<String>();
   zkServers.add("zookeeper1:2181"); zkServers.add("zookeeper2:2181"); zkServers.add("zookeeper3:2181");
   final SolrClient client = new CloudSolrClient.Builder(zkServers, Optional.empty()).build();
 

Usage example when Solr data is stored in a ZooKeeper chroot:

    final List<String> zkServers = new ArrayList<String>();
    zkServers.add("zookeeper1:2181"); zkServers.add("zookeeper2:2181"); zkServers.add("zookeeper3:2181");
    final SolrClient client = new CloudSolrClient.Builder(zkServers, Optional.of("/solr")).build();
  

Parameters:

zkHosts - a List of at least one ZooKeeper host and port (e.g. "zookeeper1:2181")

zkChroot - the path to the root ZooKeeper node containing Solr data. Provide java.util.Optional.empty() if no ZK chroot is used.

Method Detail

withLBHttpSolrClientBuilder

public CloudLegacySolrClient.Builder withLBHttpSolrClientBuilder(LBHttpSolrClient.Builder lbHttpSolrClientBuilder)

Provides a HttpClient for the builder to use when creating clients.

withLBHttpSolrClient

public CloudLegacySolrClient.Builder withLBHttpSolrClient(LBHttpSolrClient loadBalancedSolrClient)

Provides a LBHttpSolrClient for the builder to use when creating clients.

withCollectionCacheTtl

public CloudLegacySolrClient.Builder withCollectionCacheTtl(int seconds)

Sets the cache ttl for DocCollection Objects cached.

Parameters:

seconds - ttl value in seconds

sendUpdatesOnlyToShardLeaders

public CloudLegacySolrClient.Builder sendUpdatesOnlyToShardLeaders()

Tells CloudLegacySolrClient.Builder that created clients should be configured such that CloudSolrClient.isUpdatesToLeaders() returns true.

See Also:

sendUpdatesToAnyReplica(), CloudSolrClient.isUpdatesToLeaders()

sendUpdatesToAnyReplica

public CloudLegacySolrClient.Builder sendUpdatesToAnyReplica()

Tells CloudLegacySolrClient.Builder that created clients should be configured such that CloudSolrClient.isUpdatesToLeaders() returns false.

See Also:

sendUpdatesOnlyToShardLeaders(), CloudSolrClient.isUpdatesToLeaders()

sendUpdatesToAllReplicasInShard

@Deprecated
public CloudLegacySolrClient.Builder sendUpdatesToAllReplicasInShard()

Deprecated.

Never supported

This method has no effect.

In older versions of Solr, this method was an incorrectly named equivilent to sendUpdatesToAnyReplica(), which had no effect because that setting was ignored in the created clients. When the underlying CloudSolrClient behavior was fixed, this method was modified to be an explicit No-Op, since the implied behavior of sending updates to all replicas has never been supported, and was never intended to be supported.

See Also:

sendUpdatesOnlyToShardLeaders(), sendUpdatesToAnyReplica(), CloudSolrClient.isUpdatesToLeaders(), SOLR-6312

sendDirectUpdatesToShardLeadersOnly

public CloudLegacySolrClient.Builder sendDirectUpdatesToShardLeadersOnly()

Tells CloudLegacySolrClient.Builder that created clients should send direct updates to shard leaders only.

UpdateRequests whose leaders cannot be found will "fail fast" on the client side with a SolrException

See Also:

sendDirectUpdatesToAnyShardReplica(), CloudSolrClient.isDirectUpdatesToLeadersOnly()

sendDirectUpdatesToAnyShardReplica

public CloudLegacySolrClient.Builder sendDirectUpdatesToAnyShardReplica()

Tells CloudLegacySolrClient.Builder that created clients can send updates to any shard replica (shard leaders and non-leaders).

Shard leaders are still preferred, but the created clients will fallback to using other replicas if a leader cannot be found.

See Also:

sendDirectUpdatesToShardLeadersOnly(), CloudSolrClient.isDirectUpdatesToLeadersOnly()

withParallelUpdates

public CloudLegacySolrClient.Builder withParallelUpdates(boolean parallelUpdates)

Tells CloudLegacySolrClient.Builder whether created clients should send shard updates serially or in parallel

When an UpdateRequest affects multiple shards, CloudLegacySolrClient splits it up and sends a request to each affected shard. This setting chooses whether those sub-requests are sent serially or in parallel.

If not set, this defaults to 'true' and sends sub-requests in parallel.

build

public CloudLegacySolrClient build()

Create a CloudLegacySolrClient based on the provided configuration.

getThis

public CloudLegacySolrClient.Builder getThis()

Description copied from class: SolrClientBuilder

The solution for the unchecked cast warning.
