Hi all, Apologies for the delay in sharing our recent updates due to business trips and project deadlines over the past few days. Here’s the update about our recent work at Timecho on IoTDB:
[IoTDB Development Tracker] - Fixed a query bug when data from a single device spans multiple regions. - Fixed errors when performing FIRST or LAST aggregation on results after a JOIN query. - Optimized execution performance of the UNION operator. - Optimized the Pipe procedure to combine historical and real-time processing when creating a new region. - Optimized Pipe to include .mods files when splitting TsFiles. - Enhanced Pipe source configuration to support multiple paths separated by commas in prefix/path. - Fixed concurrency issues in time series model inference. - Fixed concurrency issues in LAST queries for the table mode. - Fixed single-device cross-region issue in the tree mode. - Added new functions for handling binary objects. - Fixed incorrect handling of Chinese table names in DeviceCache during writes. - Fixed an issue where password reuse check failed on the first login due to old password not being recorded when creating a new user. - Fixed a memory leak in the C++ client. - Fixed a resource leak in the ConfigNode RPC server. [Calls for Community Participation] - Table mode adaptation for Telegraf, DataEase, Grafana, DataX, SeaTunnel and ThingsBoard. [Public Events] - On 23 Sep 2025 at the Beyond IoT 2025 Conference in Cologne, Germany, Christofer Dutz from ToddySoft delivered a talk named *"There is no silver bullet: How do I get my OT data?**"*, where he introduced the idea of implementing TsFile on edge devices in the industry and store the data in IoTDB, aiming at managing time series data more efficiently. [1] - On the same day at the conference, Pengcheng Zheng from Timecho delivered a talk named *"**Rethinking Time-Series Analysis: When Database and AI Converge**"*, where I introduced recent updates of IoTDB, including new table mode, time series foundation models in IoTDB, etc. [2] [3] [1] https://beyond-iot.de/veranstaltung-83700-0-there-is-no-silver-bullet-wie-komme-ich-an-meine-ot-daten.html [2] https://beyond-iot.de/veranstaltung-83738-0-zeitreihenanalyse-neu-gedacht-wenn-datenbank-und-ki-verschmelzen.html [3] https://thuml.github.io/timer/ Best regards, Pengcheng The Timecho Team
