Zilla

Exposes Kafka topics as REST, SSE, gRPC, MQTT, or WebSocket endpoints without broker-side code, as demonstrated in the runnable examples like http.kafka.crud and mqtt.kafka.proxy.

Routes and behaviors are defined in a single zilla.yaml file, enabling easy management and reducing the need for custom integration code, as shown in the detailed configuration example.

Integrates with Apicurio or Karapace to validate JSON, Avro, and Protobuf payloads at the proxy layer, centralizing validation and improving data governance.

Uses a zero-copy, flyweight architecture with per-CPU-core workers to minimize latency and GC overhead, as described in the architecture section for near-zero latency overhead.

Provides JWT-based authentication with continuous stream authorization for SSE, plus Prometheus metrics and OpenTelemetry tracing, handling cross-cutting concerns in a sidecar deployment.
