Note:TencentDB for Redis CKV Edition is currently unavailable. We recommend TencentDB for Redis Memory Edition for you.
TencentDB for Redis CKV Edition (cluster architecture) provides dual-replica cluster instances, which break the single-thread bottleneck to meet your business needs for large capacity or high performance. CKV Edition (cluster architecture) is compatible with Redis 3.2 protocols and commands and supports up to 128 shards of 12 GB–48 TB capacity.
CKV Edition (cluster architecture) only supports the password format: instance id:password
. For example, if your instance ID is crs-bkuza6i3 and the password is abcd1234, the connection command is redis-cli -h IP address -p port -a crs-bkuza6i3:abcd1234.
pttl
in CKV Edition is second, which is different from Redis Community Edition.subscribe
/psubscribe
takes up a certain amount of memory, which affects the addition of a new subscription, but does not affect the publish of the subscribed channel.Commands supported by CKV Edition (cluster architecture):
