devel/py-isal 1.8.0

This package provides Python bindings for the ISA-L library. The Intel(R) Intelligent Storage Acceleration Library (ISA-L) implements several key algorithms in assembly language. This includes a variety of functions to provide zlib/gzip-compatible compression.

python-isal provides the bindings by offering four modules:

• isal_zlib: A drop-in replacement for the zlib module that uses ISA-L to accelerate its performance.
• igzip: A drop-in replacement for the gzip module that uses isal_zlib instead of zlib to perform its compression and checksum tasks, which improves performance.
• igzip_threaded offers an open function which returns buffered read or write streams that can be used to read and write large files while escaping the GIL using one or multiple threads. This functionality only works for streaming, seeking is not supported.
• igzip_lib: Provides compression functions which have full access to the API of ISA-L's compression functions.
