Getting to Know GeminiDB Redis API

This section describes GeminiDB Redis product type and instance type, helping you quickly create and connect to a GeminiDB Redis instance.

**Table 1** Product types
Product Type	Scenario	Supported Instance Type
Standard	Stable and low-latency performance is provided, suitable for common scenarios such as advertising and recommendation, gaming, e-commerce, and Internet of Vehicles (IoV).	Proxy cluster Redis Cluster Primary/Standby
Capacity-oriented	Large-capacity key-value storage is provided, suitable for average performance requirements and expectations of low costs.	Cluster

**Table 2** Instance types
Instance Type	Scenario	Reference
Cluster	With a sharded cluster architecture, a proxy cluster instance can be connected through proxies and is compatible with a single Redis node, Redis Sentinel, and Redis Cluster. The cluster instance has strong horizontal scaling capabilities and can handle millions of QPS and dozens of terabytes of data. A Redis Cluster instance uses a sharded architecture and can be directly connected to Redis Cluster. This type of instance can greatly reduce latency while improving performance.

Primary/Standby	Primary/standby instances are compatible with single-node instances and can connect to a sentinel node. This instance type is used when hash tags are unavailable.	Buying and Connecting to a Primary/Standby Instance

Connection Methods

Data Admin Service (DAS) enables you to manage instances on a web-based console, simplifying database management and improving working efficiency. You can connect and manage instances through DAS. By default, you have the permission of remote login. DAS is secure and convenient for connecting to GeminiDB Redis instances.

**Table 3** Connection on DAS
Method	Scenario	Remarks
DAS	You can log in to an instance on the console without using an IP address.	Easy to use, secure, advanced, and intelligent By default, you have the permission of remote login. DAS is secure and convenient for connecting to DB instances.
