pmemkv-python

Python bindings for pmemkv. Currently functionally equal to pmemkv in version 1.0. Some of the new functionalities (from pmemkv 1.1) are not yet available.

All known issues and limitations are logged as GitHub issues or are described in pmemkv's man pages.

Dependencies

• Python 3.6 or later
  • along with python3-setuptools
• python3-dev(el) - header files and a static library for Python
• libpmemkv-dev(el) - at least in version 1.0 - native key/value library

Installation

Start by installing pmemkv (currently at best in version 1.0.2 or 1.1) in your system.

git clone https://github.com/pmem/pmemkv-python
cd pmemkv-python

If pmemkv is installed in default directory (e.g. /usr):

sudo python3 setup.py install

or to rather install it locally (in '/home/user_name/.local/lib/python3.X/site-packages'):

python3 setup.py install --user

If pmemkv is in some other directory:

python3 setup.py build_ext --library-dirs=<path_to_pmemkv_lib_dir> --include-dirs=<path_to_pmemkv_include_dir>
python3 setup.py install --user

Testing

Python bindings includes automated test cases. Use following command to run test cases:

cd tests
python3 -m pytest -v pmemkv_tests.py

Examples

We are using /dev/shm to emulate persistent memory in examples.

They can be found within this repository in examples directory. To execute examples:

PMEM_IS_PMEM_FORCE=1 python3 basic_example.py
PMEM_IS_PMEM_FORCE=1 python3 restAPI/run_example.py

Documentation

After installation, docs can be generated using sphinx (to install, run: pip3 install sphinx) by executing commands:

cd doc
make html
