Apache Pulsar

What is Apache Pulsar?

Apache Pulsar is a cloud-native, distributed messaging and event streaming platform originally created by Yahoo! and now a top-level Apache Software Foundation project. Pulsar was designed from the ground up to be a multi-tenant, high-performance, durable messaging system that can be used for both traditional messaging use cases and event streaming.
