Embodiment Construction

[0050] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0051] The invention provides a method for storing list data. Such as figure 1As shown, the list data to be stored is data composed of characters, and each character corresponds to a serial number, and each serial number can form a digital serial number of the list data. For example, if the list data is "products on sale in the street", the number corresponding to "production" is 1, ...

Abstract

The invention provides a list data storage method and related equipment, and belongs to the technical field of data storage, and the method comprises the following steps: setting the number of bits of bitmaps in each storage area as a preset number; obtaining a digital number of to-be-stored list data; determining a target storage area corresponding to the list data in each storage area; when the number is smaller than or equal to the preset number, determining a target bit corresponding to the number on the bitmap; and setting the value on the target bit as a preset value. According to the method and the device, the numerical number of the list data has the corresponding bit in the bitmap, the value of the bit is set as the preset value to represent that the list data is stored, the bit is one-eighth byte, and the storage space occupied by storing the list data is small; the number of bits of the bitmap in the storage area is set to be the preset number, the preset number is smaller than the maximum number of the bits contained in the storage area, and storage resources occupied by list data storage are further reduced.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method for storing list data and related equipment. Background technique [0002] The list data in the blacklist or whitelist can be used to solve problems such as authority verification, business blacklist and whitelist mechanism, etc. The storage of list data is a common requirement in system development. [0003] In a large system, due to the huge amount of list data and the intersection of different matching conditions of black and white list data, more list data will be generated. For example, the system needs to form list data for the combination of pictures, logos, types, and scopes. When there are many combinations of logos, types, and scopes, the number of list data obtained by combining logos, types, and scopes is exponential. The system needs to consume a large amount of storage resources to store the list data, that is, storing the list data takes up a large ...
