Abstract: A hard disk includes a manager, a managed component, a management interface a network interface, and a system on chip (SOC). The management interface receives an external management command. The manager performs an operation according to the received external management command on a managed component corresponding to the received external management command, and returns an operation result through the management interface to the cloud server. The network interface receive an external read/write operation command sent by the cloud server. The SOC performs a read/write operation according to the received external read/write operation command and returns a read/write operation result through the network interface.

Abstract: A method and apparatus for processing join query is disclosed. The method includes: determining a frequent table combination whose emergence frequency in a historical query record is greater than a preset value, and the table combination includes a join key and tables that are joined by using the join key; creating a clustered index according to information about the join key in the frequent table combination; and performing a shuffle operation according to an index column in the clustered index, and saving records that have a same index column value into at least one data block to form a table cluster corresponding to the frequent table combination.
