No. DataImportHandler runs inside of Solr itself so it does not need to use HTTP. It reads databases using Jdbc and uses API calls to create and load documents into Solr. Benefits over custom solutions would include speed (no HTTP/XML parsing overhead) and ofcourse all benefits of open source software apply :)
