36 Krypton learned that the industrial Internet of Things time series database management system and related service provider "Tianmou Technology Timecho" recently announced the completion of nearly 100 million yuan in angel round financing, led by Sequoia China and Gobi Ventures , Koala Fund, cloud wisdom followed the investment. This round of funds will be mainly used for open source product research and development, the construction of open source community , and the creation and expansion of the core technical team.

Timecho was founded in October 2021 by the top international open source project Apache IoTDB and the core team of Apache PLC4X. It provides 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 also the only time series database project of the Apache Foundation in . 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 Zhiyan Consulting Report, the size of my country's database market in 2020 was 24.09 billion yuan, and is expected to grow to 68.802 billion by 2025. Yuan. 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 various types such as relational database management systems, temporal 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 on Timecho has rapidly expanded, 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 information data, so they often used relational database to manage it. With the development of industrial Internet , the data perceived by machine equipment is considered to be the next industrial revolution. One of the driving forces and raw materials for upgrade, the management of these data has also become an important means to improve the quality and efficiency of industrial production and strive for excellence.

However, the data generated by industrial machinery and equipment has the characteristics of rapid generation frequency, heavy dependence on collection time, multiple measurement points and large amount of information. Traditional databases cannot effectively store, process and query time series data. Therefore, time series database management is Demand 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. It is lightweight and ready-to-use, and can be integrated with existing big data. Deep ecological integration has obvious advantages in writing performance, data compression ratio, query performance, query richness, and scalable time series calculations.

It is worth mentioning that Apache IoTDB is the first product in the field of time series database 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 information systems, people were responsible for both filling in data and reading the data. In the Internet of Things, terminal devices are responsible for generating data. People in the cloud are using data.

"Therefore, we need to consider how to make IoTDB realize cross-device, edge-cloud collaboration cost." said Huang Xiangdong, PMC Chair of the Apache IoTDB community.

IoTDB has made a lot of optimizations and innovations in data query, including improving query efficiency, solving query richness, reducing memory space, etc. For example, as early as 2017, the team proposed an aggregate query index for actual data, which can greatly reduce disk storage space and update sequence indexes 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 achieves lossless data storage. At the same time, it provides pre-indexed information based on time series in the query process, and efficiently filters out meaningless objects. data.

From an industry perspective, in addition to Timecho, there are other domestic startups that are also making plans in time series databases. Compared with other players, Zheng Pengcheng believes that the company's differentiated competitive advantages are mainly in the following points:

First, the international advantage, Timecho is based on the international Apache (the largest international open source software foundation) IoTDB open source project was established, but it is not limited For IoTDB, the company team also has core developers specializing in industrial data collection such as Apache PLC4X, which can provide customers with full life cycle management products for industrial data. The company has now expanded to multiple international users.

The second is the team advantage. The company team brings together a group of database core technology scientists and industry senior experts from Tsinghua University, UC Berkeley, Microsoft , Germany's Fraunhofer Institute, Germany's Frankfurt Energy Group, etc., with more than ten years of research and service The experience of industrial users has deep know-how from data generation to usage methods and features, and they can condense these experiences into IoTDB products.

The third is ecological advantage, . In the past few years, IoTDB has brought together German Bosch , Siemens , Pugman and domestic Tsinghua , Ali , Oriental Guoxin, UFIDA, Huawei , MCC, 360 and a group of ecological partners, covering all life cycle stages from IoT data collection to application. While Timecho continues to vigorously develop IoTDB, it can rely on its partners to provide users with more and richer services.

In the field of time series data management, IoTDB team members hold more than 30 invention patents in China, the United States, and Europe. In 2022 alone, the team published 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 will soon be applied. In terms of the

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 to users who have higher requirements for data, stability, functions, etc. In the future, the company will also build standardized database products based on user needs in different fields, and provide customers with other value-added functions such as algorithm libraries, customized services, and cloud hosting.

At this stage, the company has been maintaining cooperative research and development processes with domestic and foreign companies, such as Bosch, Siemens, 360, Alibaba, Huawei and other companies. In terms of implementation, Timecho has successively received commercial cooperation orders in the fields of energy, aerospace, intelligent manufacturing, power grids, etc. It also focuses on steel, Internet of Vehicles, petrochemicals, meteorology, finance, new energy vehicles and other industries.

In the next year, Timecho will continue to accelerate the development of IoTDB products, integrating more cutting-edge technologies to better handle high-end and complex equipment, as well as IoT data management of massive common devices. The company will also focus on providing a more adaptable and efficient commercial version of IoTDB for unique hardware environments 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.
