Overview
What is Apache Pulsar?
Apache Pulsar is a cloud-native, multi-tenant, high-performance solution for server-to-server messaging and queuing built on the publisher-subscribe (pub-sub) pattern. Pulsar combines the best features of a traditional messaging system like RabbitMQ with those of a pub-sub system like Apache Kafka — scaling up or down dynamically without downtime. It’s used by thousands of companies for high-performance data pipelines, microservices, instant messaging, data integrations, and more.
Originally developed by Yahoo, Pulsar is under the stewardship of the Apache Software Foundation.
Architecture
A Pulsar instance is composed of one or more Pulsar clusters. This instance uses an instance-wide ZooKeeper cluster (configuration) for a store to retain information that pertains to multiple clusters, such as geo-replication
and tenant-level security policies.
Why use Apache Pulsar?
- It’s open source ecosystem
- It’s structured to scale elastically.
- It provides extensive documentation.
- Pulsar offers multi-tenancy, which allows multiple groups of users to share the cluster.
- It offers management tooling built-in.
- Pulsar combines modularity and performance with multi-tenancy, geo-replication, consolidating Queueing and Streaming capabilities into one…
