LZ4 Bindings for Python
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 lz4
The library is pretty simple to use:
>>> import lz4 >>> compressed_data = lz4.dumps(data) >>> data == lz4.loads(compressed_data) True >>>
Methods and Constants
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. "0.7.0" True >>>
Is it fast ?
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 : 5.146867s
Because 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…)
