This is fairly tricky question, because there's definitely a bunch of databases that are not used widely in production environments, but are technically open source and implement some sort of parallel query functionality. For example there's MonetDB (which is using basically a Mozilla license), which supports parallel queries since ~2012 or so. There's also C-Store (Vertica is a commercial fork), and H-Store (VoltDB is a commercial fork) - AFAIK both support query parallelism. Although they are experimental / research project (and most companies use the commercial forks in production), they use BSD license so technically they are open source. Also, Stonebraker cooperated on both those projects so neglecting them would be particularly annoying. regards -- Tomas Vondra http://www.2ndQuadrant.com PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-advocacy mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-advocacy
