Looking at DataImporter I'm not sure if it's possible to import using a standard <add><doc>... xml document representing a document add operation. Generating <add><doc> is quite expensive in my application and I have cached all those documents into a text column into MySQL database. It will be easier for me to "push" all updated documents directly from Database instead passing via multiple xml files posted in "stream" mode to Solr.
Thank you. Dario.
