How do I use the hash algorithm of TencentDB for Tendis Cluster Edition?
The hash algorithm of the Tendis Cluster Edition is the same as that in the Redis Cluster Community Edition, i.e., HASH_SLOT = CRC16(key) mod 16384. For more information, please see Redis Cluster Specification. Will my business be interrupted during instance scaling?
