Hi Kudu community, I'm happy to announce that the Kudu PMC has voted to add Lifu He, Yao Xu, and Yao Zhang as new committers and PMC members.
Lifu has worked on a variety of patches, from dead container deletion in the block manager, to metric aggregation in the master, to several performance improvements in the rowset interval tree and DMS. He's currently working on a (very exciting and very ambitious) prototype for secondary indexing via bitmap indexes. In short, Lifu's contributions are varied, and has also been helping other users on Slack and WeChat. Yao (Xu)'s largest contribution thus far has been the "split key range" functionality which improves scan parallelism in Spark jobs. He's also made a number of other contributions, such as the extra configuration properties framework for tables, and a new tablet placement policy based on user-defined dimension labels. Yao (Zhang)'s contributions have included server-side bloom filter predicate support and, more recently, performance improvements for updates. Lifu works at NetEase (one of the largest Internet and video game companies in the world) where he helps operate their Kudu clusters. Both Yao Xu and Yao Zhang work at Ant Financial (Alipay Inc.) where they also help operate their very large Kudu deployments. All three have been instrumental in growing Kudu's presence within China as well as helping new Chinese users come up to speed with Kudu. Please join me in congratulating Lifu, Yao, and Yao!
