What AWS Glue Schema Registry is

AWS Glue Schema Registry centrally manages and evolves schemas for data streams used by streaming applications. It provides serializers and deserializers so producers and consumers can share schemas for data serialization. Supported formats include Avro v1.11.4, JSON Schema Draft-04, Draft-06, and Draft-07, and Protocol Buffers proto2 and proto3; Protobuf extensions and groups are not supported. Eight compatibility modes are available: NONE, DISABLED, BACKWARD, BACKWARD_ALL, FORWARD, FORWARD_ALL, FULL, and FULL_ALL. Supported features include schema auto-registration, sourcing schemas through metadata, IAM compatibility, and optional ZLIB compression. Documented integrations include Apache Kafka, Amazon MSK, Kinesis Data Streams, Amazon Managed Service for Apache Flink, AWS Lambda, AWS Glue streaming, and Apache Kafka Streams. The documented Kinesis Producer and Client Library integration supports Java, not multiple languages. Client API communication uses TLS over HTTPS, and schemas are encrypted at rest with an AWS KMS service-managed key. Use is free, subject to account quotas: 100 registries and 10,000 schema versions per Region, plus 10 metadata key-value pairs per schema version per Region.
