Transactional File Systems
In an article I wrote two years ago I've discusses reasons why to store files in a relational database, based on the premise that file systems are "fast but dumb" regarding transactional features. Journaling file systems are interesting for many reasons, but it does not provide the level of transactions available in the database systems - .e.g. individual transactions are atomic but you can't group them into bigger transactions, it's not possible to do a rollback, you can't use it within an XA transaction, etc. How did the situation change since the time I wrote the article?
