The hash algorithm of the Redis Cluster Edition is the same as that in the a Redis Community Edition cluster, i.e.,
HASH_SLOT = CRC16(key) mod 16384. For more information, please see Redis Cluster Specification.
|Memory Edition (Standard Architecture)||0.25–60 GB|
|Memory Edition (Cluster Architecture)||12 GB–4 TB|
|CKV Edition (Standard Architecture)||4–384 GB|
|CKV Edition (Cluster Architecture)||12 GB–48 TB|
Redis Standard Architecture (zero-replica) does not provide high availability. Other editions of Redis adopt a master/slave replication structure, where data reliability is ensured by hot backup plus daily cold backup of the data.
On the TencentDB for Redis backend, the backup cluster performs full and incremental data backup, and persistence is done on the slaves which is virtually imperceptible to the online business.
That is used by the TencentDB for Redis instance in maintaining its data structure.
You can perform OPS and management operations in the TencentDB for Redis Console. If you need to use a visual tool, use a CVM instance as a jump server to provide an access address.
This can be implemented through custom monitoring and alarming. For more information, please see Monitoring and Alarming.
No. Multiple databases can be set on one Standard Architecture or Cluster Architecture instance.
