The record

Purpose: Centrally discovers, controls, and evolves data stream schemas for streaming applications.
Serialization: Provides serializers and deserializers so producers and consumers can share schemas for data serialization and deserialization.
Formats: Supports 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.
Schema evolution: Supports eight compatibility modes: NONE, DISABLED, BACKWARD, BACKWARD_ALL, FORWARD, FORWARD_ALL, FULL, and FULL_ALL.

Kinesis limitation: The documented Kinesis Producer Library and Kinesis Client Library integration supports Java and does not provide multi-language support.
Security: Client API communication uses TLS encryption over HTTPS, and schemas are encrypted at rest with an AWS KMS service-managed key.
