It turns out to be quite difficult to scale traditional, ACID-compliant relational database systems on cheap, shared-nothing scale-out architectures, and thus these systems drop some of the ACID guarantees in order to achieve shared-nothing scalability (letting the application developer handle the increased complexity that programming over a non-ACID compliant system entails). Database: Transactions: ACID Compliance The following is taken from PostgreSQL vs. MySQL [webtechniques.com, Sept 2001]. I've reproduced only the section on ACID, leaving out the comparison of PostgreSQL and MySQL, which is somewhat dated.
