Plugin to interact with schema-registry using API Schema registry.

Simplify schema registration under specific subjects (topic names) and conduct seamless compatibility checks. This plugin streamlines the integration of Avro schemas, enhancing your local testing process and ensuring smooth execution in integration tests and CI pipelines. Use it now to effortlessly manage enrollment and schema validation in your Kafka ecosystem!

This plugin is licensed under the MIT License - see the License file for details.

The plugin simplifies kafka consumer testing when using avro schemas, and also provides additional features such as compatibility check. It can be used in local testing, as well as in integration tests or CI.

Features:

• registration of schemes under subjects
• compatibility check

build.gradle.kts:

plugins {
    id("io.github.rudikone.avroschema-wizard-plugin") version <version>
}

avroWizardConfig {
    schemaRegistryUrl = "some_url"
    searchAvroFilesPaths = setOf("../some/search/path/1", "../some/search/path/2")
    topicToSchema = mapOf("some-topic-1" to "SomeSchemaName1", "some-topic-2" to "SomeSchemaName2")
    subjectNameStrategy = "TopicNameStrategy"
}

run

gradle registerAllSchemas

The task will search for files with extension .avsc, whose names (without extension) are passed as topicToSchema map values, in the directories passed to searchAvroFilesPaths, and register schemas by appropriate subjects depending on the subjectNameStrategy value.

Output: Registered <schema_name> with id: <id_from_registry> for <topic_name>

If a schema with the same name is registered under multiple subjects, the id will be assigned to it once. See Documentation

run

gradle checkCompatibility

The task will search for files with extension .avsc, whose names (without extension) are passed as topicToSchema map values, in the directories passed to searchAvroFilesPaths, and check the compatibility of the new versions of the schemas by appropriate subjects depending on the subjectNameStrategy value.

OR

run

gradle checkCompatibility --subject=<subject-name> --schema=<schema-name>

The task will search for a file with the extension .avsc, whose name (without extension) is passed as a command line argument (schema), in the directories given in searchAvroFilesPaths, and check if the passed schema is compatible with the schema under the subject passed as a command line argument (subject).

If the subject does not exist, an error will be thrown!

Output: Schema <schema_name> is (not) compatible with the latest schema under subject <subject_name>

See example module. Run docker-compose, testing plugin tasks. For convenience, you can use schema-registry-ui (http://localhost:8002/ in your browser).
