In their own words
AutoMQ
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.
