Hi all, This is the draft of the IoTDB quarter report, let me know if I missed anything.
## Description: The mission of Apache IoTDB is the creation and maintenance of software related to an IoT native database with high performance for data management and analysis. ## Project Status: Current project status: Ongoing with high activity. Issues for the board: no. ## Membership Data: Apache IoTDB was founded 2020-09-16 (4 years ago) There are currently 78 committers and 31 PMC members in this project. The Committer-to-PMC ratio is roughly 5:2. Community changes, past quarter: - Yongzao Dan was added to the PMC on 2025-08-18 - Zhijia Cao was added as committer on 2025-07-29 - Junzhi Peng was added as committer on 2025-07-06 - Yuchen Ding was added as committer on 2025-07-07 ## Project Activity: We have just released versions 2.0.4 and 2.0.5, which significantly enhance IoTDB's query and analysis capabilities: - Building on UDSF and UDAF, we have expanded support to include UDTF; added support for window functions and RPR in standard SQL, providing users with convenient built-in syntax to explore trends between different rows; and extended support for ASOF JOIN (this syntax originally comes from the Python pandas library). - Users can create table-model views based on tree-model data, enabling existing tree-model users to perform analytical queries using standard SQL for table models without data migration. - The AINode comes with built-in support for the Sundial time-series large model[1], and also supports one-click fine-tuning using user data. ## Community Health: Overall community health is good. - In July, we held the IoTDB 2.0 launch event, where we introduced numerous new features of IoTDB 2.0 to everyone. - Since some of the features developed in the previous quarter are defined in standard SQL, there were established specifications to reference, and thus not many conflicting points required discussion on the mailing list. Naturally, any existing discussions took place directly during the PR reviews on GitHub, so dev@iotdb.apache.org had a 43% decrease in traffic in the past quarter (103 emails compared to 178). We are also guiding community contributors to send the function definitions of these non-controversial development items to the mailing list, so that interested members of the community can participate together. - Contributions from Timecho are now summarized weekly and sent to the mailing list.
