Overview
This package provides bindings for the lz4 compression library by Yann Collet.
Install
The package is hosted on PyPI:
$ pip install lz4 $ easy_install lz4
Usage
The library is pretty simple to use:
>>> import lz4 >>> compressed_data = lz4.dumps(data) >>> data == lz4.loads(compressed_data) True >>>
Methods
The bindings provides some aliases too:
>>> import lz4 >>> lz4.LZ4_compress == lz4.compress == lz4.dumps True >>> lz4.LZ4_uncompress == lz4.uncompress == lz4.loads True >>>
Is it fast ?
Yes. Here are the results on my 2011 Macbook Pro i7 with 128kb random data:
$ python tests/bench.py Data Size: Input: 131072 LZ4: 131601 Snappy: 131087 LZ4 / Snappy: 1.003921 Benchmark: 200000 calls LZ4 Compression: 3.651002s Snappy Compression: 8.066482s LZ4 Decompression: 1.482934s Snappy Decompression : 3.193481s
Important note
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…)
