There's a good chance that JDBC is trying to read the entire result set (all three million rows) into memory before sending any of that info to Solr. Set the batchSize to -1 for MySQL so that it will stream results to Solr as soon as they are available, and not wait for all of them. Here's more info on the situation, which frequently causes OutOfMemory problems for users: http://wiki.apache.org/solr/DataImportHandlerFaq?highlight=%28mysql%29|%28batchsize%29#I.27m_using_DataImportHandler_with_a_MySQL_database._My_table_is_huge_and_DataImportHandler_is_going_out_of_memory._Why_does_DataImportHandler_bring_everything_to_memory.3F Thanks, Shawn
