Hi,
In solr 8.3.1 source, I see the following , which I assume could be the
reason for the issue "Max requests queued per destination 3000 exceeded for
HttpDestination",
solr/solrj/src/java/org/apache/solr/client/solrj/impl/Http2SolrClient.java:
private static final int MAX_OUTSTANDING_REQUESTS = 1000;
solr/solrj/src/java/org/apache/solr/client/solrj/impl/Http2SolrClient.java:
available = new Semaphore(MAX_OUTSTANDING_REQUESTS, false);
solr/solrj/src/java/org/apache/solr/client/solrj/impl/Http2SolrClient.java:
return MAX_OUTSTANDING_REQUESTS * 3;
how can I increase this?
