Virtuoso Cluster Edition is as described by Sebastian in an earlier post to this thread [1]. Online that's behind our LOD Cloud cache which hosts 40 Billion+ triples, but still using ridiculously cheap hard-ware for the share-nothing cluster. As Jerven has already articulated [2], the single-server open source edition of Virtuoso can also scale to 40 Billion+ triples as demonstrated by Uniprot amongst others. There's a publicly available Google Spreadsheet that provides insights into a variety of Virtuoso configurations that you can also look at regarding resource requirements [3]. Bottom line, Virtuoso has no fundamental issues with performance, scale, or security (most haven't hit this bump yet, but its coming!) regarding RDF-data deployed in line with Linked Data principles. We are always opened to collaboration with anyone (or group) seeking to fully exploit the power and promise of a Semantic Web derived from Linked Data :) Links: [1] https://lists.wikimedia.org/pipermail/wikidata/2019-June/013132.html -- Sebastian Hellman comment [2] https://lists.wikimedia.org/pipermail/wikidata/2019-June/013143.html -- Jerven Bolleman comment [3] https://docs.google.com/spreadsheets/d/1-stlTC_WJmMU3xA_NxA1tSLHw6_sbpjff-5OITtrbFw/ <https://docs.google.com/spreadsheets/d/1-stlTC_WJmMU3xA_NxA1tSLHw6_sbpjff-5OITtrbFw/edit?ouid=112399767740508618350&usp=sheets_home&ths=true> -- Virtuoso configurations sample spreadsheet [4] https://hub.docker.com/u/openlink/ -- Docker Hub offerings [5] https://aws.amazon.com/marketplace/pp/B00ZWMSNOG -- Amazon Marketplace BYOL Edition [6] https://aws.amazon.com/marketplace/pp/B011VMCZ8K -- Amazon Marketplace PAGO Edition [7] https://github.com/openlink/virtuoso-opensource -- Github [8] http://download.openlinksw.com -- Download Site -- Regards, Kingsley Idehen Founder & CEO OpenLink Software Home Page: http://www.openlinksw.com Community Support: https://community.openlinksw.com Weblogs (Blogs): Company Blog: https://medium.com/openlink-software-blog Virtuoso Blog: https://medium.com/virtuoso-blog Data Access Drivers Blog: https://medium.com/openlink-odbc-jdbc-ado-net-data-access-drivers Personal Weblogs (Blogs): Medium Blog: https://medium.com/@kidehen Legacy Blogs: http://www.openlinksw.com/blog/~kidehen/ http://kidehen.blogspot.com Profile Pages: Pinterest: https://www.pinterest.com/kidehen/ Quora: https://www.quora.com/profile/Kingsley-Uyi-Idehen Twitter: https://twitter.com/kidehen Google+: https://plus.google.com/+KingsleyIdehen/about LinkedIn: http://www.linkedin.com/in/kidehen Web Identities (WebID): Personal: http://kingsley.idehen.net/public_home/kidehen/profile.ttl#i : http://id.myopenlink.net/DAV/home/KingsleyUyiIdehen/Public/kingsley.ttl#this
