On the afternoon of November 29, 2020, IoTDB held its first community meetup since the project graduated from Apache. more than thirty people were present on site, and the event was live-streamed on bilibili throughout the session, gaining high popularity.
At the meetup, lecturers gave talks on various topics around IoTDB community status, the principle of IoTDB and the application of practical scenarios, and offline and online participants also actively interacted with the lecturers. let's take a look at the great talks of the lecturers! 2. Recap of the Talk 13:30-13:40 Introduction to the development of Apache IoTDB community by Xiangdong Huang Mr. Huang Xiangdong introduced the growth of IoTDB since its open source. At present, 89 contributors from 5 countries have contributed code to IoTDB, bringing together an active user base of 500+ people, and dozens of users have used and tested it. The next major goal is to release the distributed version and version 1.0! 13:40- 14:10 Practical Analysis of Talkweb IoT Platform with Apache IoTDB by Bin Huang Mr. Huang Bin introduced Hunan Talkweb information in its IoT platform using Apache IoTDB as a time-series data storage engine, and shared the deployment and implementation cases of the system in Hunan China Tobacco, which has been online for hundreds of devices and hundreds of thousands of measurement points. 14:10-14:30 Introduction of Apache Local Community ALC Beijing by Willem Ning Jiang Mr. Jiang Ning firstly introduced the original purpose of setting up ALC Beijing is to better help the development of open source in China, and then briefly sorted out the development of ALC Beijing in the recent year. Finally, Mr. Jiang sent out invitations to all participating members of Apache and looked forward to your participation. 14:30-15:00 Massive Sequence Processing: Distributed Metadata Management Technology for IoTDB by Chao Wang BONC (Beijing Orient Ntl Comn Sc & Tch Co Ltd) distributed time-series database group is deeply involved in the development of IoTDB distributed. As the department head, Mr. Chao Wang mainly introduces the distributed architecture of IoTDB from three aspects firstly, and then gives a detailed explanation from the hierarchical management of metadata and caching mechanism. 15:30-16:00 Empathy: Embracing Competition and Collaborating as Essential Skills of Open Source by Jiansheng Li Mr. Li believes that open source is a product of society and culture, which uses the Internet and technology as a medium to build connections and trust between people, which in fact has high requirements for participating members: respect for diversity, empathy, rational analysis, decision making, cross-cultural communication, etc.. Among them, empathy is a crucial part, Mr. Li mainly talked about four points about this understanding: 1, in open source,why there are competing relationships, 2, what is empathy, 3, open source project development in the conflict resolution rules, 4, why is empathy vital? Then Mr. Li used the case of Microsoft embracing open source and Apache SkyWalking to further explain his point. 16: 00-16:30 Introduction to the Advanced Use of IoTDB and the Principles Behind it by Kai Feng Xue Mr. Xue Kaifeng mainly explains the content related to IOTDB advanced use and principles, including IoT data challenges, IoT data model, write principles and optimization strategies, query principles and optimization strategies, TsFile structure, typical query scenarios and principles, and finally, the IoTDB philosophy included in the memory control module - out-of-the-box. 16: 30- 17:00 X-DB Real-Time Database Usage by Wanhong Li Mr. Li Wanhong reported the usage of xdb based on IoTDB in power plants. By upgrading HBase to IoTDB, it greatly reduces the complexity of operation and maintenance, supports the load scenario of 300,000 points for a single device, and performs well. 17:00 -17:30 IoTDB for DIgital Twin Platform in Germany by Julian Feinauer Connected via Zoom, Julian presents a case study of Pragmatic Minds in Germany using IoTDB to support digital twins. 3.
