However, large-scale data systems that implement ACID semantics are extremely expensive, as they require huge infrastructures behind them.

In the last decade, there has been a growing interest in creating cost-effective, large-scale data systems. This interest is driven primarily by those in need of data collection, such as the data-mining needs of social websites that generate enormous amounts of click-stream data or scientific datasets. Much of this data is read only, so...
