key in SQL Server has metadata containing a URL link to the key inside the control plane. Hence all the encryption and decryption operations of the Database Encryption Key (DEK) are done inside the controller. SQL Server stores the public key, but only to identify the asymmetric key and ...
redis-trib 向源节点发送 cluster getkeysinslot < slot > < count > 命令,获得最多 count 个属于槽 slot 的键值对的键名(key name)。 对于步骤 3 获得的每个键名,redis-trib 都向源节点发送一个 migrate <target_ip> <target_port> <key_name> 0 < timeout > 命令,将被选中的键原子地从源节点迁移...
