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
