A Netflix Hystrix port to Python.
This is a work in progress, please feel free to help!
For more information see the Netflix Hystrix Wiki documentation.
To know more see the Netflix Hystrix Wiki How it works section documentation.
It's ALPHA version and only support launching a group of commands inside an executor pool.
It depends on concurrent.futures, new in Python version 3.2 and enum, new in Python version 3.4. It uses futures and enum34 backports to run in Python version 2.7, 3.3 and 3.4.
Create a virtualenv:
mkproject --python=<fullpath_to_python_3.2+> hystrix-py
Get the code:
git clone https://github.com/wiliamsouza/hystrix-py .
Install it:
python setup.py develop
The last command enter your code in "Development Mode" it creates an
egg-link
in your virtualenv's site-packages
making it available
on this environment sys.path
. For more info see setuptools development-mode
setup.py
will handle test dependencies, to install development use:
pip install -e .[dev]
python setup.py test
Code to be isolated is wrapped inside the run()
method of a hystrix.Command
similar to the following:
from hystrix import Command
class HelloWorldCommand(Command):
def run(self):
return 'Hello World'
This command could be used like this:
command = HelloCommand()
# synchronously
print(command.execute())
'Hello World'
# asynchronously
future = command.queue()
print(future.result())
'Hello Wold'
# callback
def print_result(future)
print(future.result())
future = command.observe()
future.add_done_callback(print_result)
