Method, apparatus, electronic device and readable storage medium for data query

An electronic device, wherein the electronic device comprises:

• at least one processor;
• and
• a memory communicatively connected with the at least one processor;
• wherein,
• the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to perform a data query method, wherein the method comprises:
• obtaining a hash code of content to be queried;
• obtaining data units corresponding to the hash code and brief information of the content to be queried;
• wherein each of the data units is used to store content having a same hash code;
• comparing, in parallel, the brief information with a plurality of brief information in the data units to determine whether they are the same;
• and
• according to the content to be queried and stored content which is stored in the data units and has the same brief information as the content to be queried, determining whether the content to be queried is stored in the data units.

A non-transitory computer-readable storage medium storing computer instructions therein, wherein the computer instructions are used to cause the computer to perform a data query method, wherein the method comprises:

• obtaining a hash code of content to be queried;
• obtaining data units corresponding to the hash code and brief information of the content to be queried;
• wherein each of the data units is used to store content having a same hash code;
• comparing, in parallel, the brief information with a plurality of brief information in the data units to determine whether they are the same;
• and
• according to the content to be queried and stored content which is stored in the data units and has the same brief information as the content to be queried, determining whether the content to be queried is stored in the data units.
