It is Python binding of
easyflow project, which
makes is easy to launch interconnected processes in one
dataflow.json5
file.
Install this package using pip.
pip install -U git+https://github.com/jerry73204/easyflow-python.git
Here walks through the simple pub/sub example in the directory.
On the publisher side, it creates a sender according to the dataflow file.
flow = pyeasyflow.load_dataflow('dataflow.json5')
sender = flow.build_sender('publisher')
sender.send(b'DATA')
The subscriber side creates a listener from the same dataflow file.
flow = pyeasyflow.load_dataflow('dataflow.json5')
def callback(payload):
print(payload)
listener = flow.listen('subscriber', callback)
Launch two scripts simultaneously.
