Schema Registry serves as a central hub to handle and validate schemas for message data related to Kafka topics. It also manages serialization and deserialization of data over the network. This aids producers and consumers in maintaining data consistency and compatibility as schemas change. Schema Registry by Upstash is API compatible with the Confluent Schema Registry. That means you can use it with:
  • io.confluent.kafka.serializers.KafkaAvroSerializer/Deserializer
  • io.confluent.connect.avro.AvroConverter
  • Any UI tool that supports Confluent Schema Registry.
See How to to learn how to configure the schema registry to use in various scenarios. See Compatibility page for details of compatibility settings. See Rest API in case you want to directly access the schema registry.
