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: none. ## Membership Data: Apache IoTDB was founded on 2020-09-16 (5 years ago). There are currently 83 committers and 33 PMC members in this project. The Committer-to-PMC ratio is roughly 5:2. Community changes, past quarter: - Xuan Wang was added to the PMC on 2026-08-17. - No additional committers were added after the previous report. The latest addition remains Xinhao Gu on 2026-06-04. ## Project Activity: - Apache IoTDB 2.0.10 was released in July.[1] The release expanded Table Model SQL support with common table expressions, set operations, and new built-in functions; introduced a C client SDK with parameter binding and multi-node failover; improved cluster administration and observability; and strengthened AINode model management and CPU inference stability. - Development on the Table Model continued toward richer in-database analytics and easier ecosystem integration. The community added the read_tsfile table function for querying external TsFiles,[2] lateral column aliases in SELECT lists,[3] Prometheus-style rate, increase, irate, and delta aggregate functions,[4] and an FFT table function for frequency-domain analysis.[5] - Reliability and deployment flexibility remained important focus areas. User, role, and permission operations were integrated into the metadata lease/self-fencing framework for high availability.[6] - An IoTDB Edge distribution was also merged for a future release; it runs ConfigNode and DataNode in one JVM with resource-constrained defaults validated on Raspberry Pi-class devices.[7] ## Community Health: Overall community health is good. - [email protected] had almost same traffic as the past quarter (253 emails compared with 255). Discussions covered the 2.0.10 release and future roadmap, Table Model analytics, the IoTDB Edge distribution, high availability, and new client and ecosystem integrations. - The Google Summer of Code project for integrating the IoTDB 2.x Table Model with ThingsBoard made substantial progress. Telemetry, latest-value, and attribute DAOs, together with aggregation support, documentation, and a write-path benchmark, were merged into apache/iotdb-extras.[8] - Following a community discussion and vote, the apache/iotdb-client-rust repository was created. It now contains a working client for both the Tree and Table Models, including session pools, multi-node failover, tablet writes, paged query decoding, and TLS support.[9] - On August 22, the 2026 Time Series Data Technology Innovation Summit was held in Beijing. The event brought together users, developers, researchers, and industry practitioners for discussions on time-series data management, AI, open-source innovation, and Apache IoTDB use cases.[10] [1] https://github.com/apache/iotdb/releases/tag/v2.0.10 [2] https://github.com/apache/iotdb/pull/17951 [3] https://github.com/apache/iotdb/pull/17960 [4] https://github.com/apache/iotdb/pull/18334 [5] https://github.com/apache/iotdb/pull/18006 [6] https://github.com/apache/iotdb/pull/18425 [7] https://github.com/apache/iotdb/pull/18538 [8] https://github.com/apache/iotdb-extras/tree/master/iotdb-thingsboard-table [9] https://github.com/apache/iotdb-client-rust [10] https://timecho.com/archives/1787553862296 Best regards, -------------------- Yuan Tian
