Riquet is a standalone, Go-based replacement for the Confluent Schema Registry. It serves the Confluent v1 REST contract and existing Avro, Protobuf, and JSON Schema clients without requiring a JVM, database operator, or vendor-specific Kafka distribution.

Two storage profiles are built into the same binary:

• PVC: embedded bbolt storage for one durable writer; Kafka is not needed.
• Kafka HA: a compacted Kafka topic, transactional fencing, primary election, authenticated mutation forwarding, and locally served reads on every caught-up replica.

The compatibility claim is tested continuously against pinned Confluent Platform 8.3.0 and maintained Java, Go, Python, and .NET clients. See compatibility/manifest.json for the machine-readable scope and intentional exceptions.

go build -o riquet ./cmd/riquet
./riquet --listen :8081 --data ./riquet.db

Then register a schema through the standard API:

curl --fail-with-body \
  -H 'Content-Type: application/vnd.schemaregistry.v1+json' \
  --data '{"schema":"{\"type\":\"string\"}"}' \
  http://127.0.0.1:8081/subjects/example-value/versions

Operational guides:

• Deployment and availability
• Backup, restore, and migration
• Security
• Compatibility scope
• Performance and tested limits
• Incident response

make fmt-check
make test
make test-race
go test ./test/helm -v

Docker-backed compatibility and HA suites use the e2e build tag. The pinned Confluent images are test dependencies only and are not redistributed.
