This package provides bindings for the lz4 compression library by Yann Collet.
Code specific to this project is covered by the BSD 3-Clause License
The package is hosted on PyPI:
$ pip install lz4
$ easy_install lz4The library is pretty simple to use:
>>> import lz4
>>> compressed_data = lz4.dumps(data)
>>> data == lz4.loads(compressed_data)
True
>>>The bindings provides some aliases too:
>>> import lz4
>>> lz4.LZ4_compress == lz4.compress == lz4.dumps
True
>>> lz4.LZ4_uncompress == lz4.uncompress == z4.decompress == lz4.loads
True
>>> lz4.VERSION == lz4.__version__ # e.g. "0.8.0"
True
>>>Yes. Here are the results on my 2011 Macbook Pro i7 with lz4.c as input data: :
$ python tests/bench.py
Data Size:
Input: 24779
LZ4: 10152 (0.41)
Snappy: 9902 (0.40)
LZ4 / Snappy: 1.025247
Benchmark: 200000 calls
LZ4 Compression: 9.737272s
Snappy Compression: 18.012336s
LZ4 Decompression: 2.686854s
Snappy Decompression : 5.146867sBecause LZ4 doesn't define a container format, the python bindings will insert the original data size as an integer at the start of the compressed payload, like most bindings do anyway (Java...)
