Does DCS for Redis Support Multi-DB?
DCS's support for multiple databases (multi-DB) is as follows:
- Single-node, read/write splitting, and master/standby DCS Redis instances: Multi-DB is supported. By default, there are 256 databases, numbering 0–255. The default database is DB0. Multi-DB is used for data isolation. The size of each database is not evenly allocated. As a result, one database may fully occupy the memory of the instance.
- Proxy Cluster: There is only one database by default.
- For details about how to create a Proxy Cluster instance with multiple databases, see How Do I Create a Multi-DB Proxy Cluster Instance?
- For details about how to enable multi-DB for a single-DB Proxy Cluster instance, see What Are the Constraints on Implementing Multiple Databases on a Proxy Cluster Instance?
- Redis Cluster DCS instances: Multi-DB is not supported. There is only one database (DB0).
The number of databases cannot be changed, and the size of each database cannot be customized.
