kafka-schema-registry 0.0.4

Kafka and schema registry integration

kafka-schema-registry

This library allows you to create topics on Kafka topics, associated with a Confluent Schema Registry, and publish messages on them.

It takes care of:

• creating the topic
• publishing the associated schema (or updating an existing one)
• serializing and publishing messages to Kafka

It works with kafka-python, and extra arguments are forwarded to it.

Installing

pip install kafka-schema-registry

Usage

from kafka_schema_registry import prepare_producer

SAMPLE_SCHEMA = {
    "type": "record",
    "name": "TestType",
    "fields" : [
        {"name": "age", "type": "int"},
        {"name": "name", "type": ["null", "string"]}
    ]
}


producer = prepare_producer(
        ['localhost:9092'],
        f'http://schemaregistry',
        topic_name,
        1,
        1,
        value_schema=SAMPLE_SCHEMA,
)

producer.send(topic_name, {'age': 34})
producer.send(topic_name, {'age': 9000, 'name': 'john'})

Running the tests

The test requires Docker in order to start a local Redpanda instance.

• make start-redpanda to start the server
• make test to configure a virtualenv and run the tests
