Non-blocking MongoDB driver for Tornado or asyncio
Project description
- Info:
Motor is a full-featured, non-blocking MongoDB driver for Python Tornado and asyncio applications.
- Author:
A. Jesse Jiryu Davis
About
Motor presents a callback- or Future-based API for non-blocking access to MongoDB. The source is on GitHub and the docs are on ReadTheDocs.
“Motor uses a clever greenlet-based approach to fully support both synchronous and asynchronous interfaces from a single codebase. It’s great to see companies like MongoDB produce first-party asynchronous drivers for their products.”
—Ben Darnell, Tornado maintainer
“We use Motor in high throughput environments, processing tens of thousands of requests per second. It allows us to take full advantage of modern hardware, ensuring we utilise the entire capacity of our purchased CPUs. This helps us be more efficient with computing power, compute spend and minimises the environmental impact of our infrastructure as a result.”
—David Mytton, Server Density
“We develop easy-to-use sensors and sensor systems with open source software to ensure every innovator, from school child to laboratory researcher, has the same opportunity to create. We integrate Motor into our software to guarantee massively scalable sensor systems for everyone.”
—Ryan Smith, inXus Interactive
Installation
$ pip install motor
Dependencies
Motor works in all the environments officially supported by Tornado or by asyncio. It requires:
Unix, including Mac OS X. Windows is not supported.
PyMongo 2.8.0 exactly.
Python 2.6 or later.
backports.pbkdf2 for faster authentication with MongoDB 3.0+, especially on Python older than 2.7.8, or on Python 3 before Python 3.4.
See requirements for details about compatibility.
How To Ask For Help
Issues with, questions about, or feedback for Motor should be sent to the mongodb-user list on Google Groups.
For confirmed issues or feature requests, open a case in Jira in the “MOTOR” project. Please include all of the following information:
Detailed steps to reproduce the problem, including your code and a full traceback, if possible.
What you expected to happen, and what actually happened.
The exact python version used, with patch level:
$ python -c "import sys; print(sys.version)"
The exact version of PyMongo used:
$ python -c “import pymongo; print(pymongo.version); print(pymongo.has_c())”
The exact Tornado version, if you are using Tornado:
$ python -c "import tornado; print(tornado.version)"
The operating system and version (e.g. RedHat Enterprise Linux 6.4, OSX 10.9.5, …)
Documentation
Motor’s documentation is on ReadTheDocs.
To build the documentation, install sphinx and do cd doc; make html.
Examples
See the examples on ReadTheDocs.
Testing
Run python setup.py test. Tests are located in the test/ directory. In Python 2.6, unittest2 is automatically installed.
