Google File System. ... CloudStore supports incremental scalability,
replication, checksumming for data integrity, client side fail-over and access

My impression is that HDFS has at least one and maybe two orders of

usable from Python?

Sorry, that would be HDFS :)

options something probably works.  It looks like third-party SWIG and
ctypes wrappers for libhdfs are out there.    The command line is
pretty complete, too: <a href="
