Transaction support in a log-structured file system

The design and implementation of a transaction manager embedded in a log-structured file system are described. Measurements indicate that transaction support on a log-structured file system offers a 10% performance improvement over transaction support on a conventional read-optimized file system. When the transaction manager is embedded in the log-structured file system, the resulting performance is comparable to that of a more traditional, user-level system. The performance results also indicate that embedding transactions in the file system need not impact the performance of nontransaction applications
