The Baidu DBA team has played a significant role in the CockroachDB community, transitioning from open source contributors in 2015 to internal advocates who have developed various production applications. Their enthusiasm culminated in a collaboration with Cockroach Labs to organize the CockroachDB China Community Conference, reflecting the growing interest and adoption of CockroachDB in China's open source community. The conference featured talks from prominent companies like Baidu, Alibaba, and Tencent, focusing on CockroachDB's technical architecture, use cases, and future developments, while Baidu shared their internally developed tools for CockroachDB integration and data migration. Despite CEO Spencer Kimball's absence, a video introduction was provided, highlighting the excitement and potential for continued community growth and innovation in leveraging CockroachDB's capabilities for business expansion.
