Another Python binding for LMDB. Built with Cython
LMDB Python
Another Python bindings for LMDB.
This repo serves as a practice for me to learn how to use 3rd-party C/C++ libraries in Python using Cython. The compiled C extension is statically linked against the master branch of OpenLDAP here.
Installation
From wheels:
pip install lmdb-python -f https://gau-nernst.github.io/lmdb-python/
The following pre-built wheels are provided (64-bit only)
| Platform | Architecture |
|---|---|
| Linux | manylinux: x86_64 and aarch64; musllinux: x86_64 and aarch64 |
| macOS | x86_64 (Intel) and arm64 (Apple Silicon) |
| Windows | AMD64, x86, and ARM64 |
Supported Python versions depend on cibuildwheel. macOS arm64 is Python 3.8+, Windows ARM64 is Python 3.9+, and the rest are Python 3.6+.
Due to GHA runners' limitations, the following wheels are not tested, thus not guaranteed to work:
- musllinux_aarch64
- macosx_arm64
- win_arm64
From source: Install directly from this GitHub repo
pip install git+https://github.com/gau-nernst/lmdb-python.git
Alternatively, you can clone the repo locally and install from the local clone (remember to clone recursively to get OpenLDAP LMDB C source)
git clone --recursive https://github.com/gau-nernst/lmdb-python.git
cd lmdb-python
pip install .
If you want to build against a specific version of LMDB, checkout the corresponding tag in the openldap submodule before installing the package
# assume you are inside 'lmdb-python' directory now
cd openldap
git checkout LMDB_0.9.30
Usage
from lmdb_python import Database
db = Database("test_db")
db.put(b"key", b"value")
assert db.get(b"key") == b"value"
Run tests
Install pytest using either pip or conda, then run it.
pytest -v
