What Is GeminiDB?

GeminiDB is a distributed, multi-model NoSQL database service with decoupled storage and compute. It is highly available, reliable, secure, and scalable and delivers excellent performance. It can be deployed quickly and provide capabilities like backup, restoration, monitoring, and alarm reporting.

GeminiDB is compatible with mainstream NoSQL APIs, such as Cassandra, DynamoDB, MongoDB, InfluxDB, and Redis and provides high read/write performance at low costs. It is specifically suited for IoT, meteorology, Internet, and gaming sectors.

How Do I Select an API?

Different APIs provide different functions. You can select one of them based on your service requirements and scenarios.

**Table 1** Scenario description
API	Compatible API	Scenario	Description
GeminiDB Redis API	Key-value API: Redis	GeminiDB provides high-concurrency and low-latency service access, and ultimate elastic scaling capabilities to cope with service peaks. Common user scenarios include gaming, RTA-based advertising, recommendation systems, e-commerce, and education.	GeminiDB Redis API is a scalable Key-Value (KV) database that supports the Redis protocol and offers a larger storage capacity than memory. It is stable, cost-effective, and has low latency. Unlike other databases, it does not require standby nodes and has an impressive data compression ratio of 4:1. Additionally, it includes enterprise-level features such as hash field expiration, Bloom filter, FastLoad, and memory acceleration.
GeminiDB Influx API	Time series API: InfluxDB	GeminiDB Influx API is widely used to monitor resources, workloads, IoT devices, and industrial production processes, evaluate production quality, and trace faults.	GeminiDB Influx API is a cloud-native, InfluxDB-compatible NoSQL time series database, which uses Huawei-developed architecture with decoupled storage and compute. GeminiDB Influx API can read and write a large volume of time series data concurrently and store it with compression algorithms. The database service then allows you to query the data using SQL-like statements and supports multi-dimension aggregate computing and visual analysis on it. GeminiDB Influx API also provides high write performance, scalability, a good compaction rate, and excellent query performance.
GeminiDB Cassandra API	Wide-column API: Cassandra and DynamoDB	GeminiDB Cassandra API can store terabytes of data and can handle millions of queries per second. It provides strong consistency, making it well suited to massive storage scenarios, such as manufacturing, meteorology, and the Internet.	GeminiDB Cassandra API is a cloud-native NoSQL database that uses a decoupled storage and compute architecture developed by Huawei. It is compatible with the Cassandra ecosystem and supports Cassandra Query Language (CQL), which gives you SQL-like syntax. It is secure, reliable, scalable, and easy to manage and can provide high read/write performance.
GeminiDB Mongo API	Document-oriented API: MongoDB	GeminiDB Mongo API gives you 3 times the read and write performance of MongoDB and can handle millions of queries per second. It can also store a huge number of documents, images, and social video/audios, and massive IoT/IoV data, making it an excellent choice for sectors like the Internet, IoT, gaming, and finance.	GeminiDB Mongo API is a cloud-native, MongoDB-compatible NoSQL database service, which uses Huawei-developed architecture with decoupled storage and compute. This flexible, scalable, and reliable database is designed for enterprise-grade performance and can be managed on a visual platform.
