On behalf of the Apache Phoenix PMC, I'm please to announce that Ethan Wang has accepted our invitation to become a committer. He's behind some of the great new 4.12 features of table sampling [1] and approximate count distinct [2] along with contributing to the less sexy work of helping to stabilize our unit tests.
Please give Ethan a warm welcome to the project! James [1] https://phoenix.apache.org/tablesample.html [2] https://phoenix.apache.org/language/functions.html#approx_count_distinct
