python-hll

A Python implementation of HyperLogLog whose goal is to be storage compatible with java-hll, js-hll and postgresql-hll.

NOTE: This is a fairly literal translation/port of java-hll to Python. Internally, bytes are represented as Java-style bytes (-128 to 127) rather than Python-style bytes (0 to 255). Also this implementation is quite slow: for example, in Java HLLSerializationTest takes 12 seconds to run while in Python test_hll_serialization takes 1.5 hours to run (about 400x slower).

Runs on: Python 2.7 and 3
Free software: MIT license
Documentation: https://python-hll.readthedocs.io.

Getting started

$ mkvirtualenv python_hll
$ python setup.py develop
$ pip install -r requirements_dev.txt

Run tests:

$ make lint
$ make test-fast

To run one test file or one test:

$ py.test --capture=no tests/test_sparse_hll.py
$ py.test --capture=no tests/test_sparse_hll.py::test_add

To run slow tests:

$ make test
