Big data streaming platform and event ingestion service capable of millions of events per second with Kafka compatibility, Capture to Blob or Data Lake, and partition-based scaling

Enterprise message broker with queues and pub/sub topics, supporting sessions, transactions, duplicate detection, dead-letter queues, and AMQP 1.0 protocol for interop

Fully managed event routing service implementing the CloudEvents 1.0 spec, with MQTT pub/sub for IoT, HTTP push delivery, dead-lettering, retry policies, and native filters supporting millions of events per second across Azure, partner, and custom source topics

Globally-distributed message queue with per-producer fan-out to multiple consumers, at-least-once delivery, configurable batching and retries, automatic dead-letter queues, and zero egress charges between Queues and Workers

Ingest streaming event data over HTTP or from Worker bindings, transform with SQL, and write the result to R2 as Apache Iceberg tables or partitioned Parquet/JSON files for downstream warehouse and analytics tools. Open-beta as of 2026.
