Data query method and query client

Abstract

Embodiments of the invention provide a data query method and a query client. The method comprises the following steps of: receiving a first query request by the query client, wherein the first query request carries a target business identifier and is used for querying data corresponding to the target business identifier; determining a target directory identifier corresponding to the target business identifier by the query client, wherein the target directory identifier belongs to M directory identifiers; determining whether the target directory identifier has a corresponding table item or notby the query client; if the target directory identifier has the corresponding table item, determining whether the table item corresponding to the target directory identifier has a table item comprising the target business identifier or not by the query client; and if the table item corresponding to the target directory identifier does not have the table item comprising the target business identifier, determining that data corresponding to the target business identifier does not exist in a data query system by the query client. According to the data query method and the query client, performance of existing data query schemes can be enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the computer field, and more specifically, relate to a data query method and a query client. Background technique [0002] File reputation refers to the security level of a file. A harmless file has a higher reputation level, while a malicious program has a lower reputation level. File reputation can be represented by a numerical value, and files can be identified by hash (Hash). In this way, the security vendor can query the corresponding file reputation value according to the file identifier, and then determine whether the file is safe or not according to the file reputation value. For example, if the range of file reputation is defined as 0-100, the lower the file reputation value corresponding to the file identifier, the lower the reputation, that is, the worse the security of the file. [0003] The cache of the query client can only maintain a small amount of data information, and all data infor...

Problems solved by technology

The local hit rate of the existing technology is low, which will lead to frequent triggering of remote queries. On the one hand, it takes up more network transmission resources, and on the other hand, it takes a long time to wait for the query results.

Therefore, the existing query scheme is not efficient
