Data query method and query client

Abstract

The embodiment of the invention provides a data query method and a query client. The method comprises the steps that the query client receives a first query request, and the first query request carries a target service identifier and is used for requesting to query data corresponding to the target service identifier; the query client determines a target directory identifier corresponding to the target service identifier, wherein the target directory identifier belongs to the M directory identifiers; the query client determines whether a corresponding table item exists in the target directory identifier; if the corresponding table item exists in the target directory identifier, the query client determines whether the table item including the target service identifier exists in the table item corresponding to the target directory identifier or not; and if the table item corresponding to the target directory identifier does not contain the table item containing the target service identifier, the query client determines that the data corresponding to the target service identifier does not exist in the data query system, so that the performance of an existing data query scheme can be improved.

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
