RabbitMQ vs Vitess

RabbitMQ is an open source messaging and streaming broker for application communication, including distributed microservices, real-time data, and IoT. Publishers can route messages to one or more consumers using routing, filtering, streaming, and federation. Message acknowledgements and replication across a cluster support delivery reliability, and delivery guarantees are configurable. Supported protocols include AMQP 0-9-1, AMQP 1.0, MQTT, STOMP, RabbitMQ Streams, HTTP, and WebSocket, including browser communication over WebSocket. Client libraries are available for Java, .NET/C#, Erlang, and other languages; the project also offers a community Docker image and Kubernetes operators. RabbitMQ can run in cloud or on-premises environments, on local machines and physical or virtual hardware, and in containers. Linux, Windows, and macOS are supported; z/OS, most mainframes, and systems with less than 100 MB of RAM are not. The free, self-managed Open Source RabbitMQ Server is offered under the Mozilla Public License 2.0 with best-effort community support. VMware Tanzu RabbitMQ is a commercial offering with 24/7 support and enterprise features; pricing is by contact.
