Jack asked an excellent question. What do you mean by this? Unless you're using the dataimport handler, all indexing is external to Solr. > my situation is : > > * running two indexer ( for fail over ) and two searcher. > * just use two searcher for service. > * have plan to move on Solr Cloud > > however I wonder that if I run indexing job on one of the solr cloud server, > the server’s load would be higher than other nodes. > so, I want to build index out of sold cloud but…. In SolrCloud, every shard replica will be indexing -- it's not like old-style replication, where the master indexes everything and the slaves copy the completed index. The leader of each shard will be working slightly harder than the other replicas, but you really don't need to worry too much about sending all your updates to one server -- those requests get duplicated to the other servers and they all index them, almost in parallel. For my setup (non-cloud, but sharded), I use Pacemaker to ensure that only one of my servers is running my indexing program and haproxy (plus its shared IP address). Thanks, Shawn
