One choice that hasn't been mentioned, and is perhaps worth exploring given the features raised as important here (clustering, replication, SQL-9x/200x, optimization engine, EXPLAIN, multi-column indexes, etc.). OpenLink Virtuoso Universal Server http://virtuoso.openlinksw.com/wiki/main/Main/ http://sf.net/projects/virtuoso The Open Source Edition is linked above. The Commercial version also includes Virtual DBMS features -- so you can keep your existing Oracle, MySQL, PostgreSQL, Progress, Informix, etc. repositories, and just make use of them through Virtuoso's feature set, which includes -- * Object-Relational Database for SQL, XML, RDF, and Free Text that includes Java and .NET runtime hosting * RDF store and SPARQL * WebDAV and Web Application Server * Web Services Platform for SOA * Data Access Interfaces for ODBC, JDBC, ADO.net and OLE/DB clients * Web-based administration interface and interactive developer tutorials The "what's new" blurbs for the latest two dot-releases -- > 2007-09-27: Release v5.0.2 > > This release includes 64-bit Integer support, RDF Sink Folders for > WebDAV (enabling RDF Quad Store population simply by dropping RDF > files into WebDAV), SPARUL optimizations, enhanced typed literal > support in SPARQL, automatic metadata extraction from audio binary > files, support for PHP 5.2 runtime hosting, an enhanced UI for RDF > Linked-Data deployment using URL-rewrite rules, sew Sponger > cartridges for Facebook, Freebase, Wikipedia, GRDDL, RDFa, eRDF > and more.

There are also small bug-fixes. (Yes, I work for OpenLink. No, I get no benefit if you grab the Open Source Edition, nor directly if you buy a license for the Commercial Edition or any services associated with either. I would like to hear from you about both positive and negative experiences with either.)
