Metamorphosis (MetaQ) is a high-availability, high-performance distributed messaging middleware written in Java, originally developed at Taobao and similar to Apache Kafka with various improvements. This is a personal fork published to Maven Central, used in production at companies like JD, Alipay, and Tencent.
Use cases
- distributed message queue for java services
- high throughput pub-sub messaging
- kafka-like messaging middleware
- decouple microservices with async messaging
- reliable log streaming between systems
When to choose
- you need a Kafka-like message queue on the JVM with proven production use at large Chinese internet companies
- you want a Java-native alternative to Kafka with simpler operations
When to avoid
- you need a modern, actively developed project - the latest release is from 2020 and upstream Taobao has moved to MetaQ 2.x/3.x
- you need a large community ecosystem and multi-language client support
