I do store RDF data into virtuoso. Initial data was loaded into v 6.x.x. then gradually virtuoso was uploaded to v 7.0.0 and recently it has been upgraded to v 7.1.0
When is a database gets created if you load a rdf file into virtuoso using ld_dir_all() ?? thanks sumit ________________________________________ From: Hugh Williams [hwilli...@openlinksw.com] Sent: Saturday, May 17, 2014 5:46 PM To: Purohit, Sumit Cc: virtuoso-users@lists.sourceforge.net Subject: Re: [Virtuoso-users] Using column store structure for exiting data Hi Sumit, By default all SQL tables would be created as row wise, if the ColumnStore=1 setting is in place then any new SQL tables created will be column wise, but any existing table will not be auto converted or reindexed. The one exception are the RDF_QUAD and associated tables and indexes used for storing RDF data, which are created as column wise by default when a new v7 database is created, as is best suited for hosting RDF datasets.
