pyignite_dbapi

Apache Ignite 3 DB API Driver.

Prerequisites

• Python 3.9 or above (3.9, 3.10, 3.11, 3.12 and 3.13 are tested),
• Access to Ignite 3 node, local or remote.

Installation

From repository

This is a recommended way for users. If you only want to use the pyignite_dbapi module in your project, do:

$ pip install pyignite_dbapi

From sources

This way is more suitable for developers, or if you install the client from zip archive.

1. Download and/or unzip Ignite 3 DB API Driver sources to pyignite_dbapi_path
2. Go to pyignite_dbapi_path folder
3. Execute pip install -e .

$ cd <pyignite_dbapi_path>
$ pip install -e .

This will install the repository version of pyignite_dbapi into your environment in so-called “develop” or “editable” mode. You may read more about editable installs in the pip manual.

Then run through the contents of requirements folder to install the additional requirements into your working Python environment using

$ pip install -r requirements/<your task>.txt

You may also want to consult the setuptools manual about using setup.py.

C extension

The core of the package is a C++ extension. It shares the code with the Ignite C++ Client. The package is pre-built for the most common platforms, but you may need to build it if your platform is not included.

Linux building requirements:

• GCC (and G++);
• CMake version >=3.18;
• OpenSSL (dev version of the package);
• Docker to build wheels;
• Supported versions of Python (3.9, 3.10, 3.11, 3.12 and 3.13). You can disable some of these versions, but you'd need to edit the script for that.

For building universal wheels (binary packages) for Linux, just invoke script ./scripts/create_distr.sh.

Windows building requirements:

• MSVC 14.x, and it should be in path;
• CMake version >=3.18;
• OpenSSL (headers are required for the build);
• Supported versions of Python (3.9, 3.10, 3.11, 3.12 and 3.13). You can disable some of these versions, but you'd need to edit the script for that.

For building wheels for Windows, invoke script .\scripts\BuildWheels.ps1 using PowerShell. Make sure that your execution policy allows execution of scripts in your environment. The script only works with Python distributions installed in a standard path, which is LOCALAPPDATA\Programs\Python.

Ready wheels will be located in distr directory.

Updating from older version

To upgrade an existing package, use the following command:

pip install --upgrade pyignite_dbapi

To install the latest version of a package:

pip install pyignite_dbapi

To install a specific version:

pip install pyignite_dbapi==3.1.0

Testing

NB! It is recommended installing pyignite_dbapi in development mode. Refer to this section for instructions.

Remember to install test requirements:

$ pip install -r requirements/install.txt -r requirements/tests.txt

Run basic tests

Running tests themselves:

$ pytest

Documentation

Install documentation requirements:

$ pip install -r requirements/docs.txt

Generate documentation:

$ cd docs
$ make html

The resulting documentation can be found in docs/_build/html. If you want to open the documentation locally, you can open the index of the documentation docs/_build/html/index.html using any modern browser.
