Hi Andres, By "automatically maintained indexes" I mean that FleetDB automatically and atomically updates all declared indexes when you insert, update or delete a record. You do need to declare them first though; at this point FleetDB cannot infer what indexes are needed by your application.
The key point is that you don't need to implement indexes in the application layer and suffer the corresponding complexity and possible non-atomicity, as you need to with some other non-sql datastores. - Mark On Jan 5, 12:56 am, Anders Rune Jensen <anders.rune.jen...@gmail.com> wrote: > On Tue, Jan 5, 2010 at 1:12 AM, Mark McGranaghan <mmcgr...@gmail.com> wrote: > > Hi All, > > > I'm happy to announce the alpha release of 'FleetDB', a schema-free > > database implemented in Clojure and optimized for agile development. > > > From the homepage athttp://fleetdb.org:"FleetDB offers a flexible > > and expressive data model designed for the needs of modern application > > developers; a combination of schema-free records, declarative queries, > > automatically maintained indexes, and an optimizing query planner make > > it easy to manipulate and retrieve data.
