[SciPy-User] [ANN] carray: an in-memory compressed data container
Fri Aug 20 10:29:11 CDT 2010
Announcing carray 0.1
What it is
carray is a container for numerical data that can be compressed
in-memory. The compresion process is carried out internally by Blosc,
a high-performance compressor that is optimized for binary data.
Having data compressed in-memory can reduce the stress of the memory
subsystem. The net result is that carray operations can be faster
than using a traditional ndarray object from NumPy.
Everything ;-) This is the first public release of carray, and it is
more a proof of concept to see which possibilities opens efficient
compression for in-memory data containers.
Currently carray 0.1 implements the basic container creation and
enlargeability. Multidimensional arrays are not supported yet, and
elements cannot be modified either (i.e. no `__setitem__()` support).
