No.	Term	Description
1	standard master-replica instance	A instance that is built on top of a master-replica architecture. Standard master-replica instances provide limited capacity and performance. However, you can change a standard master-replica instance to an instance of another architecture, such as a cluster or read/write splitting instance.
2	cluster instance	A instance that runs in a cluster architecture with scalability. Cluster instances provide higher scalability and performance. However, the instances provide limited features.
3	endpoint	The host address that is used to connect to Redis. The endpoint is displayed as a domain name. To obtain the endpoint, log on to the console and choose Instance Information > > Connection Information.
4	connection password	The password that is used to connect to a instance. The password is in the user:password format.
5	eviction policy	The eviction policy that is the same as that of Redis.
6	database (DB)	Each Redis instance can contain up to 256 databases: DB 0 to DB 255. By default, data is written into DB 0.
