Dear Pulsar community,

Over the last few years, the shift to real-time streaming technologies has bolstered the adoption of Pulsar and there has been a major increase in both the interest and adoption of Pulsar in 2020 alone. With Pulsar being sought out by companies developing messaging and event-streaming applications — from Fortune 100 companies to forward-thinking start-ups — the community is growing quickly.

This community growth has contributed to a new milestone for Pulsar - our 300th contributor to the Pulsar repository. This milestone is even more exciting given that we added 100 contributors in the last 8 months alone!

As many of you know, Apache Pulsar is a cloud-native messaging and event streaming platform that has experienced rapid growth since it was committed to open source in 2016. Pulsar graduated as a Top-Level Project (TLP) in September 2018, has launched 92 releases, attracted 5100+ commits from 300 contributors, received 6.5k+ stars, 1.6k+ forks, and 2.2k+ Slack users.

The influx of developers joining the Pulsar community is in large part due to the high market demand for next-generation messaging technologies, big-data insights, and real-time streaming. Top developers and industry leaders are joining the Pulsar community for the opportunity to help shape the future of this technology.

Community Events​

To meet the high demand for education and training in the Pulsar community, the community has launched some key initiatives this year. We host weekly TGIP(Thank God It's Pulsar) training, which features Pulsar thought-leaders and Pulsar PMC Members. To meet global demand, we currently host two different weekly trainings. One TGIP training runs on Pacific Time, and the other TGIP-CN training runs on Beijing Time.

We also host monthly webinars to bring together Pulsar and messaging community thought-leaders to share best practices, insights and product news. Thank Matteo Merli, Addison Higham, Joe Francis, Shivji Kumar Jha, Devin Bost, Pierre Zemb, Jesse Anderson, Sijie Guo and other speakers for contributing so much valuable knowledge.

Dear Apache Pulsar enthusiast,

As we know, when assessing the health of an open-source community, it is tempting to focus on various quantitative metrics, for example, activity, size (contributors), demographics, diversity, and so on, among which the number of contributors is a key metric for measuring the health and popularity of a project and a way to inform the trends.

And today, we are very proud to see that Apache Pulsar has attracted its 200th contributor! It is an important milestone for our community growth.

Pulsar Summit is an annual conference dedicated to Apache Pulsar community, bringing together an international audience of CTOs/CIOs, developers, data architects, data scientists, Apache Pulsar committers/contributors, and the messaging and streaming community, to share experiences, exchange ideas and knowledge about Pulsar and its growing community, and receive hands-on training sessions led by Pulsar experts.
