[jira] [Commented] (SOLR-8332) factor HttpShardHandler[Factory]'s
url shuffling out into a ReplicaListTransformer class
[ https://issues.apache.org/jira/browse/SOLR-8332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15586485#comment-15586485 ]
Noble Paul commented on SOLR-8332:
----------------------------------
{code:java}
interface ReplicaListTransformer {
public void transform(List<Replica> replicas);
public void transformUrls(List<String> shardUrls);
}
{code}
As a I look at the functionality what it should do is to choose a few replicas from the available list of replicas. Sometimes, it would like to make a choice based on some input from users. It *should not* deal with actual urls. it's the responsibility of Solr to map the urls to actual replicas
So, Lets have a much simpler interface
{code:java}
interface ReplicaFilter {
public List<Replica> filter(List<Replica> allReplicas, SolrQueryRequest req);
}
{code}
