Description

This package contains the Kafka implementation of the Input-/OutputPortPlugin interface of pypz. It enables the operators to send and receive data records in a real streaming fashion.

Check the documentation for more details.

Install

The python artifact is hosted on https://pypi.org/, so you can install it via pip:

pip install pypz-kafka-io

If you want to work on it locally, then you should install in editable mode:

pip install -e ./plugins/kafka_io

Test

You can run tests against an existing Kafka cluster, however, it is more convenient and safe to use a local test cluster.

Run the confluent image to start a local cluster

docker run --name kafka-test-cluster -d --rm -p 9092:9092 confluentinc/confluent-local

Install the subproject in editable more.

pip install -e ./plugins/kafka_io

To run the tests locally, you need to execute the following command:

python -m unittest discover .\plugins\kafka_io\test\ -p "*.py"

Delete cluster

docker stop kafka-test-cluster

Known issues

Due to the fact that the test execution is sometimes faster than the Kafka cluster, there might be failed tests. Although there are already several delays inserted into the test code, it still can happen. Try to rerun the test and give a notification to the maintainer(s). Thank you.

Build

Before you build, you will need to install the "build" package:

pip install build

Optionally, you might want to set a version for local testing. Using setuptools-scm, you can pretend a version via setting the following environment variable:

# Powershell
$env:SETUPTOOLS_SCM_PRETEND_VERSION_FOR_PYPZ_KAFKA_IO="v1.2.3"

# Linux
export SETUPTOOLS_SCM_PRETEND_VERSION_FOR_PYPZ_KAFKA_IO="v1.2.3"

Then from the subproject's root, you will need to execute the following command:

python -m build

It will create the source distribution and the wheel file in the "dist" folder.
