Hi Selvam, Using start/rows to download 10M docs is what is called deep paging. You need to either use cursors (https://lucene.apache.org/solr/guide/6_6/pagination-of-results.html <https://lucene.apache.org/solr/guide/6_6/pagination-of-results.html>) or export handler (https://lucene.apache.org/solr/guide/6_6/exporting-result-sets.html <https://lucene.apache.org/solr/guide/6_6/exporting-result-sets.html>).
