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 (Redis, DynamoDB, Cassandra, HBase, InfluxDB, and MongoDB). GeminiDB delivers high I/O performance at low costs, suitable 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: 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 compatible with Redis. A GeminiDB Redis instance delivers superior performance and can process data volumes even when they exceed the available 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 DynamoDB-Compatible API	Key-value: DynamoDB	GeminiDB DynamoDB-Compatible API is a key-value database service and is suitable for scenarios such as high-concurrency web applications, IoT, e-commerce, and retail. GeminiDB DynamoDB-Compatible API delivers consistent low-latency performance along with robust data storage and advanced query capabilities.	GeminiDB DynamoDB-Compatible API communicates with DynamoDB over HTTPS. You can run CQL queries and access GeminiDB DynamoDB-Compatible API through the SDK or CLI. GeminiDB DynamoDB-Compatible API is completely compatible with Amazon DynamoDB, so you can smoothly migrate data from DynamoDB to GeminiDB without refactoring.
GeminiDB Cassandra API	Wide-column: Cassandra	GeminiDB Cassandra instances can store terabytes of data, handle millions of QPS, and ensure strong consistency. It is ideal for high-capacity storage needs across industries that rely on large clusters, such as industrial manufacturing, meteorology, and Internet.	GeminiDB Cassandra API is a cloud-native in-house NoSQL database service with decoupled storage and compute. 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 I/O performance.
GeminiDB HBase API	Wide-column: HBase	GeminiDB HBase API excels in scenarios demanding extensive data storage, real-time queries, exceptional reliability, and seamless scalability. It is particularly suited for environments leveraging Hadoop and other advanced big data processing technologies.	GeminiDB HBase API is a distributed NoSQL database service compatible with the HBase ecosystem. It features high performance, high reliability, and robust scalability.
GeminiDB Influx API	Time series: 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 service, which uses an in-house architecture with decoupled storage and compute. GeminiDB Influx API supports highly-concurrent I/O requests, compressed storage, SQL-like queries, multi-dimensional aggregation computing, and GUI-based data analysis. It provides high write performance, robust scalability, high compression rate, and high query performance.
GeminiDB Mongo API	Document-oriented: 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 volumes of IoT/IoV data, making it an excellent choice for sectors like Internet, IoT, gaming, and finance.	GeminiDB Mongo API is a cloud-native NoSQL database service using a proprietary architecture with decoupled storage and compute. This scalable reliable database provides enterprise-grade performance and can be managed on the console.
