Subject Solr maxIndexingThreads
Date Sun, 05 Jan 2014 14:59:51 GMT
I have a solr cluster with 8 server(4 shards with one replica for each). I
have 80 client threads indexing to this cluster. Client is running on a
different machine. I am trying to figure out optimal number of indexing

Now, solrconfig.xml have a config for *maxIndexingThreads*:

"The maximum number of simultaneous threads that may be indexing documents
at once in IndexWriter; if more than this many threads arrive they will wait
for others to finish. Default in Solr/Lucene is 8. "

I want to know whether this configuration is per solr instance or per
core(or collection).
