Embodiment 1

[0036] First, please refer to figure 1 , the data processing method in the embodiment of the present application includes the following content:

[0037] S101: Obtain a target key.

[0038] S102: Determine the key type to which the target key belongs, and determine a target index area corresponding to the key type of the target key.

[0039] S103: Obtain a target index item of the target key by querying the target index area.

[0040] S104: Obtain data corresponding to the target key in the data area according to the target index item.

[0041] In this embodiment of the application, the storage medium is stored in the form of Key-Value, in other words, multiple keys are stored in the storage medium, and multiple values ​​corresponding to multiple keys are stored, wherein each value has a corresponding key.

[0042] In the technical field to which this application belongs, Key is called a key, also called a primary key; Value is a value corresponding to a key, and may also ...

Abstract

The invention provides a data processing method and a data processing device used for improving data processing efficiency and lowering consumption of system resources. The method is applied to a storage medium which stores multiple keys and Values corresponding to all the Keys. The method includes: acquiring a destination key; determining a key type of the destination key, and determining a target index area corresponding to the key type of the destination key; acquiring target index entries of the destination key by searching the target index area; acquiring data, corresponding to the destination key, in a data field according to the target index entries.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a data processing method and a data processing device. Background technique [0002] The protocol for interconnection between networks (English: Internet Protocol; IP for short) hard disk is a hard disk that provides physical communication through the IP protocol. It abandons the traditional serial connection (English: Serial Attached SCSI; abbreviation: SAS) / serial advanced technology attachment (English: Serial Advanced Technology Attachment; abbreviation: SATA) interface, making the connection between the host and the hard disk easier, There is almost no distance limit. [0003] Some current storage media, such as IP hard disks, store data in the structure of Key-Value, that is, key-value pairs. Among them, Key is the key, usually a string, and Value is the value corresponding to the key, also known as data or data content, Key-Value data is referred to as KV dat...
