Kingsoft Cloud Redis (KCS) supports primary/secondary instances and cluster instances.
Primary/secondary instances support Redis 2.8 and Redis 4.0.
A primary/secondary instance supports 1 to 64 GB data. This data volume can satisfy different levels of requirements on storage capacity and performance.
A primary/secondary instance consists of a primary node and a secondary node that work in hot standby mode.
Memory capacity (GB) | Maximum number of connections allowed |
---|---|
1 | 10,000 |
2 | 20,000 |
4 | 30,000 |
8 to 64 | 40,000 |
Cluster instances support Redis 3.0 and Redis 4.0.
You can use a cluster instance in scenarios where the data volume exceeds 64 GB. A cluster instance supports 70 to 300 GB data, with increments of 10 GB. You can contact Kingsoft Cloud customer service if you require a larger capacity.
Memory capacity (GB) | Maximum number of connections allowed |
---|---|
70 to 99 | 60,000 |
100 to 149 | 80,000 |
150 to 199 | 100,000 |
200 to 249 | 120,000 |
250 to 299 | 140,000 |
300 | 160,000 |
You can create up to seven read-only replicas for a primary/secondary instance. The final charge is the sum of the charge for the primary/secondary instance and the charge for read-only replicas.
For more information about read-only replicas, see Use read-only replicas.
