DIH is single-threaded. There was once a threaded option, but it was buggy and
subsequently was removed.
What I do is partition my data and run multiple dih request handlers at the
same time. It means redundant sections in solrconfig.xml and its not very
elegant but it works.
For instance, for a sql query, I add something like this: "where mod(id,
${dataimporter.request.numPartitions})=${dataimporter.request.currentPartition}".
I think, though, most users who want to make the most out of multithreading
write their own program and use the solrj api to send the updates.

Subject: Solr 4.9 Calling DIH concurrently
Hi
I am using solr 4.9 and need to index million of documents from database. I
am using DIH and sending request to fetch by ids. Is there a way to run
multiple indexing threads, concurrently in DIH.
I want to take advantage of
<maxIndexingThreads>
parameter. How do I do it. I am just invoking DIH handler using solrj
HttpSolrServer.
And issue requests sequentially.

http://localhost:8983/solr/db/dataimport?command=full-import&clean=false&maxId=201&minId=101
