close
public void close()
Description copied from interface:SolrMetricProducer
Implementations should always callSolrMetricProducer.super.close()
to ensure that metrics with the same life-cycle as this component are properly unregistered. This prevents obscure memory leaks.from: https://docs.oracle.com/javase/8/docs/api/java/lang/AutoCloseable.html While this interface method is declared to throw Exception, implementers are strongly encouraged to declare concrete implementations of the close method to throw more specific exceptions, or to throw no exception at all if the close operation cannot fail.

getSolrMetricsContext
public SolrMetricsContext getSolrMetricsContext()
Description copied from interface:SolrMetricProducer
Implementations should return the context used inSolrMetricProducer.initializeMetrics(SolrMetricsContext, String)
to ensure proper cleanup of metrics at the end of the life-cycle of this component. This should be the child context if one was created, or null if the parent context was used.- Specified by:
getSolrMetricsContext
in interfaceSolrMetricProducer
-
newLBHttpSolrClientReq
protected org.apache.solr.client.solrj.impl.LBSolrClient.Req newLBHttpSolrClientReq(org.apache.solr.client.solrj.request.QueryRequest req, List<String> urls)
-
buildURLList
public List<String> buildURLList(String shard)
Creates a list of urls for the given shard.- Parameters:
shard
- the urls for the shard, separated by '|'- Returns:
- A list of valid urls (including protocol) that are replicas for the shard
-
getReplicaListTransformer
protected org.apache.solr.client.solrj.routing.ReplicaListTransformer getReplicaListTransformer(SolrQueryRequest req)
-
getClient
public org.apache.solr.client.solrj.SolrClient getClient()
-
initializeMetrics
public void initializeMetrics(SolrMetricsContext parentContext, String scope)
Description copied from interface:SolrMetricProducer
Initialize metrics specific to this producer.- Specified by:
initializeMetrics
in interfaceSolrMetricProducer
- Parameters:
parentContext
- parent metrics context. If this component has the same life-cycle as the parent it can simply use the parent context, otherwise it should obtain a child context usingSolrMetricsContext.getChildContext(Object)
passingthis
as the child object.scope
- component scope
