Hi! So as of 3.4 JdbcDataSource doesn't work with threads, correct?
https://issues.apache.org/jira/browse/SOLR-2233 I'm using Microsoft SQL Server, my data-config.xml has a lot of very complex SQL queries and it takes a long time to index. I'm migrating from Lucene to Solr and the Lucene code uses threads so it takes little time to index, now in Solr if I add threads=xx to my rootEntity I get lots of errors about connections being closed. Thanks a lot, Maria
