QFS Development

Welcome to QFS!  Visit us at http://quantcast.github.com/qfs.

We have developed the Quantcast File System (QFS), a high performance distributed file system, to meet our big data infrastructure needs. It evolved from the Kosmos File System (KFS), which we adopted in 2008 and started using for secondary storage. We learned many lessons and made many improvements over the years. In 2011, we committed fully when we stopped using HDFS and migrated our primary processing to QFS. Since then we’ve read or written over 4 exabytes to it. We’re confident it’s ready for other users’ production workloads. We have released QFS as open source with the hope that it will serve as a platform for experimental as well as commercial projects.
