## Description: The mission of Calcite is the creation and maintenance of software related to Dynamic data management framework ## Issues: There are no issues requiring board attention. ## Membership Data: Apache Calcite was founded 2015-10-21 (6 years ago) There are currently 53 committers and 23 PMC members in this project.

Calcite 1.27.0 was released on 2021-06-03, with important features such as InnoDB adapter, Three-valued logic for SEARCH operator and MergeUnion operator in Enumerable convention. On Apr 26th, we had online meeting to discuss the proposal of extending Calcite to an incremental query optimizer. ## Community Health: The overall activity in the community has slightly decreased in the past few months without this being worrisome. Specifically we have less active reviewers in the past 3 months. We need more committers to spend some time to review open pull requests. the number of non-committer (contributor) commits per month +---------------------+---------------------+---------------------+ | year | month | contributor_commits | +---------------------+---------------------+---------------------+ | 2021 | 4 | 14 | | 2021 | 5 | 4 | | 2021 | 6 | 5 | +---------------------+---------------------+---------------------+ top reviewers in the last 3 months +-----------+---------------------+ | committer | reviews | +-----------+---------------------+ | Julian Hyde <[email protected]> | 13 | | Stamatis Zampetakis <[email protected]> | 5 | | rubenada <[email protected]> | 1 | | amaliujia <[email protected]> | 1 | | ForwardXu <[email protected]> | 1 | | yuzhao.cyz <[email protected]> | 1 | | liyafan82 <[email protected]> | 1 | +-----------+---------------------+ Thanks, Haisheng Yuan
