Hi Calcite community members, It has been 6 years since Calcite graduated to a top level Apache project. I am so excited to witness how vivid the community has become and how far we have come.
We have seen 2 releases so far for Calcite this year (with another release v1.29.0 ongoing), with each release containing a large amount of changes. Specifically, there are many new features introduced: the InnoDB Adaptor, three-value logic for SEARCH operator, Enumerable MergeUnion operator, the UNIQUE sub-query predicate... as well as the improvements to materialized view recognition. We won't see Calcite's continuous improvements without the community members' collaboration and dedication. In terms of Calcite Avatica, we had 2 releases for Avatica and 0 releases for Avatica Go. Avatica consistently has fewer contributors and pull requests than Calcite, maybe because it has fewer users and the code hasn't changed aggressively. But more contributors and code reviewers are highly welcome and appreciated. I am glad to see that we had several technical meetups, not to mention at ApacheCon and StangeLoop, to talk about the use cases and improvements that we have done to Calcite. Many thanks to those who presented talks to give more people opportunities to know and use Calcite, and more importantly, to enrich the Calcite community. It's been a great privilege to be able to serve as Calcite's PMC chair in 2021. It's also been a big learning experience for me and I am grateful to those who trusted me and helped me in the journey. I am also extremely proud of having this opportunity to work with Calcite contributors and committers. Last but not least, we need to discuss who should be the new PMC chair of Calcite after I step down in December. I would like to nominate Ruben Quesada Lopez as the first candidate in the vote. Ruben has been a great contributor to the project. He has shown a lot of care for the Calcite project and the community, which I feel would make him a great PMC chair. To repeat questions from previous years: 1) What else are we doing well in the project? 2) What areas do we need to do better? Please take some time to share your thoughts! Thanks, Haisheng
