Hello, I started to actively participate in the Calcite community this year. I don't know the situation of the Calcite community. I can share my feelings about participating in the Calcite community this year.
At present, the Calcite community is still very healthy. Whether it is the review of PR or the answer to JIRA, you can get instant feedback, which mainly depends on individual committers and PMCs. But I found that everyone in the Calcite community can get instant feedback on emails, which is very good (but many users may not know this). If there is any disadvantage, it is that most PRs are reviewed by Mihai. Maybe we can find a way to reduce some of the pressure on Mihai. Although I am not a committer or PMC, I have also started to try to review PR. This is also a learning process for me. I like this discussion atmosphere very much. Regarding the future plans for Calcite, I can briefly describe some of the things I am doing or want to do. Perhaps this process will be long. 1️⃣ Improve the Calcite documentation. Currently, there is no documentation for some Calcite adapters. I will try to improve this part. I have tried the Calcite Arrow adapter. 2️⃣ Verify the possibility of integrating Calcite and Datafusion. 3️⃣ Write a CalciteQuery planner structure Finally, I would like to thank the Calcite community very much. I hope the community will get better and better.
