Welcome to the Pulsar Community

The Apache Pulsar community includes people from around the globe who are developing and using the messaging and streaming platform for real-time workloads. We welcome contributions from anyone with a passion for distributed systems.

About the Community

The Pulsar community is composed of members of the Project Management Committee (PMC), committers, and contributors. Committers have direct access to the source of a project and actively evolve the codebase. Contributors improve the project through submission of patches and suggestions to be reviewed by the committers. The number of committers and contributors to the project is unbounded.

A successful project requires many people to play many roles.

Some write code or documentation, while others are valuable as testers, submitting patches, and suggestions. Get involved today! All contributions to the project are greatly appreciated.
