## What it is
Apache RocketMQ is a distributed cloud-native messaging and streaming platform built for low-latency, high-throughput, financially reliable event-driven applications. Version 5.x adds AI-native capabilities such as million-scale LiteTopics for agent session management, batch consumption, and fine-grained flow control.

## Use cases
- build event-driven microservices with publish/subscribe messaging
- process financial-grade transactional messages with exactly-once semantics
- stream events between big data pipelines and analytics systems
- manage AI agent session state and multi-agent communication at scale
- decouple services asynchronously with ordered and scheduled messages
- self-host a Kafka alternative with message tracing and a dashboard

## When to choose
- you need trillion-scale message capacity with low latency and high reliability
- you require transactional, ordered, or retroactive messaging in one platform
- you want MQTT, gRPC, and JMS protocol support from a single broker
- you are orchestrating long-running AI agent sessions that must survive disconnects

## When to avoid
- you only need simple fire-and-forget queues where Redis or RabbitMQ suffices
- your team is JVM-averse since the broker and tooling are Java-based
- you need a fully managed service and cannot operate a distributed cluster
- you rely on Kafka's ecosystem of stream processing connectors exclusively

## Facets
- artifact type: service
- maturity: stable
- function: message-queue, streaming, rpc, auth, authorization, monitoring, rate-limiting
- domain: microservices, big-data, cloud-computing
- platform: windows, jvm, self-hosted, cloud
