Apache Pulsar
Apache Pulsar is a next-generation distributed messaging and streaming platform. Its superpower is its architecture: it separates compute (Brokers) from storage (BookKeeper). This makes it truly "cloud-native," allowing you to scale storage without paying for more compute. It also supports multi-tenancy out of the box.
Why use it in EDA? Pulsar solves the "scaling pain" of Kafka. It allows for instant cluster expansion without heavy data rebalancing. It also unifies the two worlds of messaging: it handles high-throughput streams (like Kafka) and complex queuing patterns (like RabbitMQ) in a single platform.
How do we use it?
- Unified Messaging: Replacing both Kafka and RabbitMQ with one system.
- Multi-tenant SaaS: Ensuring one client’s heavy traffic doesn't degrade performance for others.
- Geo-Replication: Built-in replication across global regions for disaster recovery.
