AutoMQ vs Hadron

AutoMQ is Kafka-compatible streaming software that runs Kafka on cloud object storage. It supports S3, Google Cloud Storage, Azure Blob Storage, MinIO, and Ceph, and can be deployed on premises or in private and public clouds by binary, Helm, or Docker Compose. AutoMQ states sub-10ms P99 latency and automatic scaling with traffic, including partition rebalancing across brokers. Table Topic can materialize Kafka topics as Iceberg or Delta Lake tables without ETL pipelines, for direct querying with Spark, Trino, or Flink. Managed Connector runs Kafka Connect workers in a customer’s Kubernetes environment, with logs and monitoring for throughput, task health, failures, and anomalies. The platform lists stream processing, schema registry, exactly-once delivery, a maximum 90-day retention period, and 300 connectors. Supported client languages include Java, C/C++, Go, Python, and NodeJS. Pro costs $300 a month; Enterprise pricing is by contact. There is no free plan, but a 30-day free trial requires no credit card.

Hadron is an open-source, self-hosted distributed data-storage and messaging system for ingesting events and coordinating multi-stage workflows. Streams are append-only logs with absolute ordering within each partition and horizontal scaling. Pipelines orchestrate stages over Stream data and can begin when an event matches a configured trigger. Exchanges handle ephemeral messages, while Endpoints provide general-purpose RPC handlers. Streams, pipeline inputs and outputs, and ephemeral messages use the CloudEvents 1.0 model. Hadron is designed for Kubernetes and installed with Helm and Kubernetes configuration resources; the quick start requires Helm 3.7.0 or later for OCI usage. Stream availability continues while at least one partition runs. Retention can use a configurable time policy, defaulting to seven days, or retain data indefinitely. Producers and Consumers may be written in any language, with an official Rust client and CLI. Components expose Prometheus metrics over HTTP, including Prometheus scraping and OTEL collector integrations. Token-based access creates JWTs signed by the Operator’s private RSA key, with resource-level permissions. External CLI access is still in progress, and Hadron Cloud is under construction.
