36氪 was informed that the industrial Internet of Things time series database management system and related service provider “Tianmou Technology Timecho” recently announced the completion of an angel round of financing of nearly 100 million yuan, led by Sequoia China, Gobi Ventures, Koala Fund, Cloud Wisdom Follow the vote. This round of funds will be mainly used for open source product development, open source community building, and core technical team building and expansion.
Timecho was established in October 2021 by the core team of Apache IoTDB and Apache PLC4X, the top international open source projects, to provide time series database products for customers in various industries. Apache IoTDB is the first open source time series database project in China in recent years. It was open sourced on GitHub in March 2017 and entered the Apache incubator in 2018. It is currently the only time series database project of the Apache Foundation, and its core technology originated from Tsinghua University.
With the rise of the domestic database concept and the explosion of application demand, the domestic database market has developed rapidly in recent years. According to the data of the Zhiyan Consulting report, the size of my country’s database market in 2020 is 24.09 billion yuan, and it is expected to grow to 68.802 billion yuan by 2025. Among them, the database management system, as the core of the database system, is mainly responsible for the operation and management functions of the database, including database object creation, user management, and query, addition, modification and deletion of stored data.
From the perspective of data model classification, database management systems can be divided into relational database management systems, time series database management systems, spatial database management systems, and mixed-type databases. Stimulated by the development of the Industrial Internet of Things, the market demand for time-series database management focused by Timecho has expanded rapidly and has gradually become an important software infrastructure in this field.
The main reason is that in the past, people mainly focused on the management of informatized data, so relational databases were often used for management. With the development of the Industrial Internet, the data sensed by machines and equipment is considered to be the driving force for the next industrial revolution and one of the raw materials. First, the management of these data has also become an important means to improve the quality and efficiency of industrial production and keep improving.
However, the data generated by industrial machinery and equipment has the characteristics of fast generation frequency, heavy dependence on acquisition time, and large amount of information in measurement points. Traditional databases are difficult to meet people’s effective storage, processing and query of time series data. Therefore, time series database management needs was quickly ignited.
Zheng Pengcheng, co-founder of Timecho and head of the European market, told 36氪 that Apache IoTDB is an IoT native time series database that supports device-edge-cloud collaboration. Deep integration has obvious advantages in write performance, data compression ratio, query performance, query richness, and scalable time series computing.

It is worth mentioning that Apache IoTDB is the first product in the time series database field to propose a device-edge-cloud collaborative architecture. When the Timecho team paid attention to the industrial Internet of Things scenario, they found that the generators and users of data are not the same. In the past, in the information system, people were responsible for both filling in data and looking at the data, while the Internet of Things is the terminal equipment responsible for generating data. People in the cloud are using data.
“Therefore, we need to consider how to make IoTDB work together across devices, edges and clouds. First, we must fully take care of the limited computing resources on the device side, and second, we must make full use of the computing resources on the device side to reduce the need for data management on the cloud. Cost.” said Huang Xiangdong, PMC Chair of Apache IoTDB Community.
IoTDB has done a lot of optimization and innovation in data query, including improving query efficiency, solving query richness, and reducing memory space. For example, the team proposed an aggregate query index for actual data as early as 2017, which can greatly reduce the disk storage space and update the sequence index online. In addition, IoTDB adopts the self-developed TsFile time series data storage file structure, which greatly reduces the disk storage space of user data through high compression rate, and realizes data lossless storage. At the same time, it provides pre-index information based on time series in the query link. data.
From an industry perspective, in addition to Timecho, there are other startups in China that have also deployed time series databases. Compared with other players, Zheng Pengcheng believes that the company’s differentiated competitive advantages are mainly in the following points:
One is the advantage of internationalization. Timecho was established based on the internationalized Apache (the largest international open source software foundation) IoTDB open source project, but it is not limited to IoTDB. The company team also has Apache PLC4X and other core developers specializing in industrial data collection. Provide customers with full life cycle management products for industrial data. The company has now expanded to many international users.
The second is the team advantage. The company team brings together a group of database core technical scientists and industrial senior experts from Tsinghua University, UC Berkeley, Microsoft, Germany’s Fraunhofer Institute, Germany’s Frankfurt Energy Group, etc., with more than ten years of experience in research and service for industrial users. , has deep know-how from data generation to usage, features, etc., and can condense these experiences into IoTDB products.
The third is the ecological advantage. In the past few years, IoTDB has brought together a number of ecological partners such as Germany’s Bosch, Siemens, Pugormann and domestic Tsinghua, Ali, Dongfang Guoxin, UFIDA, Huawei, MCC, 360, etc., covering everything from the Internet of Things. Data collection to the various life cycle stages of the application. While continuing to vigorously develop IoTDB, Timecho can provide users with more and richer services by relying on partners.
In the field of time series data management, IoTDB team members have more than 30 invention patents in China, the United States, and Europe. Only in 2022, the team will publish many papers related to time series data management technology at top database conferences such as VLDB and SIGMOD. Some of these technologies have been applied to Apache IoTDB, and some are about to be applied.
In terms of business model, Timecho hopes to bring together more users in an open source way. At the same time, the company will provide value-added services and technical services for users who have higher requirements for data, stability, functions, etc. In the future, the company will also build standardized database products according to the needs of users in different fields, and provide customers with algorithm libraries, customized services, cloud hosting and other value-added functions.
At this stage, the company has been maintaining the cooperative research and development process with domestic and foreign companies, such as Bosch, Siemens, 360, Ali, Huawei and other enterprises. In terms of implementation, Timecho has successively received commercial cooperation orders in the fields of energy, aerospace, intelligent manufacturing, and power grids. At the same time, it also focuses on industries such as steel, Internet of Vehicles, petrochemicals, meteorology, finance, and new energy vehicles.
In the next year, Timecho will continue to accelerate the development of IoTDB products, integrate more cutting-edge technologies to better handle high-end and complex equipment, and manage IoT data for massive common devices. The company will also focus on providing a more suitable and efficient commercial version of IoTDB for the unique hardware environment at home and abroad. In the future, it will work with ecological partners to create an industrial Internet ecosystem and solutions with IoTDB as the core.
