Embodiment Construction

[0047] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0048] In order to make it easier for those skilled in the art to understand the improvements of the embodiments of the present invention compared with the prior art, the data retrieval method in the prior art is briefly introduced below.

[0049] figure 1 An existing system architecture is shown, including a server 10 running a Java virtual machine JVM 101 and on-heap memory 102 of the JVM. The system architecture also includes a storage device 11 connected to the server 10 . Wherein, the storage device 11 may be a disk, which stores data objects.

[0050] based on figure 1 The system architecture shown, the data retrieval process in the prior art is as follows fi...

Abstract

The invention discloses a data retrieving method and a server and aims to solve the technical problem of on-heap memory overflow of a JVM server during retrieving data. The method comprises the following steps: obtaining keywords for retrieving; and retrieving data objects in pages in a memory device according to the keywords, wherein the operations performed for each page of data objects are as follows: successively storing unique identifiers of the data objects with the keywords in an on-heap memory; storing the unique identifiers stored in the on-heap memory in an off-heap memory when the number of the unique identifiers stored in the on-heap memory reaches a threshold value, and deleting the unique identifiers stored in the on-heap memory. The method and the server are used for retrieving data.

Description

technical field [0001] The present invention relates to the field of data retrieval, in particular, to a method and server for data retrieval. Background technique [0002] JVM (Java Virtual Machine, Java Virtual Machine) is a specification for computing devices, it is a fictional computer, which is realized by simulating various computer functions on an actual computer. In a large-scale service platform, there may be a large number of JVM servers inside, which are used to monitor the applications of the platform, collect data generated by various applications, and analyze various types of data. When an abnormality occurs, an alarm is issued in a timely manner, so that the maintenance personnel can deal with the problem and eliminate the fault or potential problem. [0003] In the prior art, when the JVM server retrieves the data stored in the disk, it stores all the qualified data in the disk into the in-heap memory of the JVM server. Since the capacity of the in-heap memo...
