Large Data Cloud Interoperability

This site discusses various open source projects intended to support interoperability between large data clouds. These projects include:

• Sector JNI A Java Native Interface / NIO interface to the Sector C++ client API, allowing Java clients to access the Sector distributed file system.
• PySector A Python extension to the Sector C++ client, allowing Python clients to access the Sector distributed file system.
• PySphere A Python embedding of the Sector / Sphere MapReduce framework.
• SectorFileSystem An implementation of the Hadoop File System abstraction which allows Hadoop MapReduce applications to be executed against data stored in the Sector distributed file system.
• ThriftStore A Thrift based service providing a common interface over multiple cloud storage systems.
