Hi This question has come up many times in the list with lots of variations (which confuses me a lot).
Iam using Solr 4.1. one collection , 6 shards, 6 machines. I am using CloudSolrServer inside each mapper to index my documents…. While it is working fine , iam trying to improve the indexing performance. Question is: 1) is CloudSolrServer multiThreaded? 2) Will using ConcurrentUpdateSolr server increase indexing performance? ./Zahoor
