Abstract

The invention discloses an item extracting method and device, which belong to the field of information technology and are used to save storage space in the process of acquiring items with high access frequency. The method includes: from the first sampling period to the previous sampling period of the last sampling period, performing the following steps: a. Obtain the number of visits to each entry in the current sampling period; b. For the number of visits to each entry, determine the average value of entry visits in the current sampling period; c. remove entries whose visits are less than the average in the current sampling period, and make the visits not less than the average entries in the next sampling period; repeat steps a~c until the next sampling period is the last sampling period; when the next sampling period is the last sampling period, extract the last The specified number of entries in a sample period. The invention is used for item extraction.

Description

technical field [0001] The invention relates to the field of information technology, in particular to an item extraction method and device. Background technique [0002] In a large-scale table storage structure, it is often necessary to obtain some entries with high access frequency, for example, the top 8 most frequently accessed entries, so as to analyze and control the entries. [0003] In related technologies, in order to obtain some entries with the highest access frequency, a counter and an initial count record are usually added to each entry, and the count difference between the initial count and the current count of each entry is observed and counted after a specified time, After sorting, the top N (for example, 10) entries with the highest access frequency are obtained. [0004] However, this method for obtaining items with high access frequency consumes a huge amount of storage space. Contents of the invention [0005] In order to solve the problems in the prio...
