StarTree Community
StarTree All-Stars
Leading the way forward to inspire and shape our community’s future
What is the StarTree All-Stars Program?
This global program recognizes leaders who go above and beyond, contributing extensively to the Apache Pinot and StarTree communities through knowledge sharing, advocacy, and support. All-Stars are provided access to exclusive product discussions and events and will be the first to know about significant product developments, features, and updates. They also receive limited-edition Pinot and StarTree swag!
What does it take to be a StarTree All-Star?
Contribution can include code or documentation commits, authoring blogs or whitepapers, speaking at conferences or meetups, and answering other community members' technical questions. Because every type of contribution is valuable, there's no specific “to-do” list to qualify, so the decision will be based on the applicant's overall contribution level and observable commitment.
