Ori, a high-level concurrency library for Python¶
Ori is a high-level wrapper around Python’s concurrent.futures module, designed to make multithreading and multiprocessing as easy as possible.
The tools that Ori provides are divided into several modules.
ori.asyncio – Tools to integrate Python asyncio code into a synchronous codebase, and vice-versa.
ori.concurrency – Tools to run Python functions in the background using multithreading or multiprocessing.
ori.poolchain – A way to chain function calls for parallel processing over any list or other iterable.
ori.subprocess – Tools for running external commands as subprocesses and efficiently collecting the standard output and standard error.
Frequently Asked Questions (FAQs)¶
Who made Ori?
Ori was written by James Mishra and incubated at Neocrym, a record label that uses artificial intelligence to find and promote musicians. Neocrym heavily relies on Ori to make their I/O-bound Python code run faster.
The source code for Ori is owned by Neocrym Records Inc., but licensed to Ori under the MIT License.
Why should I use Ori over directly interfacing with concurrent.futures?
The Python module concurrent.futures was introduced as a high-level abstraction over lower-level interfaces like threading.Thread and multiprocessing.Process. However, concurrent.futures merely moves the problem away from managing threads or processes to managing executors. Ori has the ambitious goal of also abstracting away the executors–making multithreading or multiprocessing no harder than writing single-threaded code.
Is Ori a good replacement for Python’s asyncio?
What do I need to know to contribute to Ori?
Ori manages itself with the Python packaging tool Poetry. You can install Poetry on your system with:
pip3 install poetry poetry install
To check that your changes to Ori’s codebase match our coding standards, and to reformat any errant code to meet our standards, run this command:
poetry run make lint
To run Ori’s unit tests in the Python virtualenv created by Poetry, just run:
poetry run make test
poetry run make tox
Where did the name “Ori” come from?
The name “Ori” is a reference to the god-like villains in the Stargate TV shows. There is no meaningful connection between the villains or concurrency.
