New databases

Following my previous blog about the future of databases, I've seen these recent posts on TheServerSide:
  • Interview on CouchDB, the Apache project for a document database, written in Erlang, with an HTTP/REST/JSON API, already mentioned in this blog. Interesting point of view at the end about BigTable. For sure a big scalable, persistent Map is certainly interesting in some very specific cases, but it is not really a database at the end.
  • Scalaris, a scalable, transactional data store for Web 2.0 services. Yet another distributed, persistent key-value system. That one shares many design ideas with BigTable, while, like CouchDB, it is written in Erlang. The big addition seems to be a better support for transactions. See OnScale for more information (videos, slides...)
