OpenGemini is a global open-source cloud-native distributed time series database designed and developed by HUAWEI CLOUD Database Innovation Lab open in new window. It provides standalone and distributed versions with excellent read and write performance and efficient data analysis capabilities. Supports mainstream development languages and multi-form deployment (such as cloud, Docker, and physical machine), integrates storage and analysis, and is easy to expand. It is dedicated to efficiently storing and analyzing massive time series data in IoT and O&M monitoring scenarios to further reduce enterprise operation and O&M costs and improve product quality and production efficiency.

Five Core Features

High Performance

Supports hundreds of millions of time lines and PB-level time series data management, tens of millions of data writes per second, and millisecond-level query response. Compared with InfluxDB, simple query performance is improved by 2 to 5 times, and complex query performance is improved by 60 times.


The MPP architecture is used. It consists of three components: ts-sql, ts-meta, and ts-store. Each component can be independently expanded and can be deployed in a large-scale cluster with more than 100 nodes.

Integrated storage and analysis

The built-in AI data analysis platform provides real-time anomaly detection capabilities for time series data and implements closed-loop management from data storage to data analysis.

Low O&M cost

More than 260 system running monitoring indicators are provided to quickly improve problem solving efficiency. The deployment does not depend on any third-party components or applications, greatly reducing O&M difficulties and costs.

High data compression ratio

Column-based storage is used to provide efficient data compression algorithm. With the same data volume, the storage cost is only 1/20 of that of relational databases and 1/10 of that of NoSQL.
