Embodiment Construction

[0033] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0034] figure 1 is a flowchart of a method for establishing an index of massive data records according to an embodiment of the present invention, such as figure 1 As shown, the method mainly includes the following steps (step S102-step S106):

[0035] Step S102, when receiving a new write file request message, obtain the current system time;

[0036] In this embodiment of the present invention, for each new request for writing a file, when obtaining the current system time, the current system time from a predetermined time (for example, 0 o'clock on January 1, 1970) to the current time can be obtained. The total time elapsed, which can be recorded as: m years, n hours, and k seconds, or, m years, ...

Abstract

Disclosed are a method and device for creating indexes for mass data records. The method includes: acquiring the current system time when a new write file request message is received; generating index keywords for a file according to the current system time and the file identifier of the file requested to be written by the write file request message; and creating an association relationship between the index keywords and the file. By way of the present invention, quick location for mass data storage can be realized.

Description

technical field [0001] The present invention relates to the field of computer and communication technologies, in particular to a method and device for establishing an index of massive data records. Background technique [0002] In the current memory database, attributes such as file name or write time are usually used as index keywords, but for the storage of massive data, indexing in this way is slow or the indexing result is not unique. For example, in the current IPTV system, stored media files are accessed through a distributed file system, and the file system uses an in-memory database to manage metadata of the file system. In the application, the system is required to support 5 million file records and 20 million chunk (CHUNK) records. If the existing indexing method is adopted, the requirement of fast positioning cannot be met. Contents of the invention [0003] The main purpose of the present invention is to provide a method and device for establishing an index of...
