务平台，解放企业生产力，加速企业数字化转 型升级。在帮助企业释放增长空间的同时，也 提供了一份具有高度可参考性的开源建设实践 样本。 06 开源创业企业 刘奇 创始人兼CEO 知名开源项目TiDB / TiKV / Codis的 作者，曾任职豌豆荚/京东，擅长分 布式数据库和分布式缓存。 黄东旭 联合创始人 兼CTO 开源分布式缓存服务Codis 的作者，资深infrastructure 工程师，开源狂热分子。 数据库 2022年开源 2019年开源 2018年开源 / TiDB TiFlash Chaos Mesh ossinsight TiKV Star:13K； Fork:2K； Contributor:392 ; https://github.com /tikv/tikv Star:1.1K； Fork:223； Contributor:113; https://github.co m/pingcap/os- 100贡献者。 TiKV：TiKV是一个分布式事务型的键值数据库，提供了满足ACID约束的分布式事务接口，并且通 过Raft协议保证了多副本数据一致性以及高可用。TiKV作为TiDB的存储层，为用户写入TiDB的数据 提供了持久化以及读写服务，同时还存储了TiDB的统计信息数据。TiKV于2018年8月被云原生计算 基金会接受为沙盒项目。2019年5月，CNCF宣布正式将TiKV从沙箱项目晋级至孵化项目。2020年

PingCAP 在开源领域的表现也是⾮常地亮眼。Top50 项⽬中上榜的项⽬有 6 个，包括由其 ⾃主设计、研发的开源分布式关系型数据库 pingcap/tidb，分布式事务型的键值数据库 tikv/tikv，⽂档项⽬ pingcap/docs-cn、pingcap/docs 等，表明 PingCAP 很重视项⽬⽂档 的建设。值得关注的项⽬是 pingcap/tidb，该项⽬的issue_comment，open_issue， 和迭代速度。SkyWalking 在按照⾃⼰的节奏，和国内外的商业化⼚商、个⼈开发者、公司⼆ 次开发团队⼀起，迅速地成熟和壮⼤。 ⻩东旭（PingCAP CTO，pingcap/tidb，tikv/tikv） TiDB 今年社区运营的重点可以分为：⽤户、开发者两块。从业务⻆度来看，可以分为项⽬打 磨和完善，⼈才的培养和⽣态建设，⽤户场景的挖掘和业务成功推进。所以，运营⼀个好的开 源社区，最重要的是以⼈为中⼼，与他们共同成⻓。 投票三个步骤。⽬前该阶段的项⽬有containerd、CoreDNS、 Envoy、etcd、Fluentd、Harbor、Helm、Jaeger、Kubernetes、Prometheus、Rook、 TiKV、TUF、Vitess 等。 CNCF 托管已毕业，正在孵化和沙盒中的项⽬。尽管 CNCF 为所有项⽬提供了⼀套共享服 务，但并未为沙盒项⽬提供实质性的营销服务，因为它们是属于早期阶段的项⽬，需要轻型中
