Transferring Avro Schemas Across Schema Registries with Kafka Connect

The SMT is used to replicate Kafka topics between separate Schema Registry clusters without overwriting pre-existing schemas, ensuring schema compatibility and consistency across environments. The transform includes a revision of the schema ID alongside the topic's replication configuration, allowing for selective transfer of schemas between clusters. This enables seamless integration of Confluent Platform with multi-datacenter environments, where Schema Registries do not require an active-passive configuration and can be shared across multiple clusters without potential schema ID collisions.
