Quantcast released a new Hadoop file system QFS:

  1. fully compatible with HDFS
  2. licensed under Apache 2.0 license
  3. written in C++
  4. while HDFS replicates data 3 times, QFS requires only 1.5x raw capacity
  5. QFS supports two types of fault tolerance: chunk replication and Reed-Solomon encoding

  6. QFS components (more details here):

    qfs-components

  7. QFS performance comparison to HDFS:

    QFS Performance Comparison to HDFS

Now I’m looking forward to hear comments from HDFS experts about QFS.
